Looking at 1996 and 1997 Camaro SS's. Used to own a '96 SS Hardtop 6spd.
Anyway, i have found a 1997 Camaro SS that is white with the orange stripes, 6 spd and hardtop. How do i find out if it is 1 of the 100 LT4 cars that were produced??? do i have to call SLP or can it be determined in the VIN or RPO codes?

Should be able to tell by the RPO's but SLP can tell you with the VIN.


Waiting on Xsta Z 28 to post in here, he has car #6. There is a thread on it here

I have LT4 #18. If you have access to the car, you should be able to verify if it was an LT4 car by the SLP options door sticker (RH Door), it should actually state LT4 SLP Car #:_ _ _ . If you look under the hood, the Emission sticker on the radiator shroud should state that the engine is an LT4. I would think those two stickers may have been overlooked or missing if it was a fake LT4.

I'm pretty sure that since SLP did the LT4 swap, the GM factory RPO decal won't have LT4 on it. CompNine's database doesn't contain any f-bods w/ RPO LT4.

I'd be interested on seeing a RPO decal on a legit LT4 car. I suspect it has LT1.

Looking at the pictures of Xsta Z's car, the RPO sitcker shows LT1. Even the SLP sticker doesn't show the LT4 on it but the emission sticker on the radiator supports shows LT4

Other than "appearance" there are no "codes" on the car to say it is a LT4 . . the intake should be red, the tail panel should have an orange 330 hp decal and the above shown decal changed by SLP.

Concerning Xsta's post; R7T is the RPO code for a '96 and '97 SS. A '96 or '97 SS must have that code or it isn't a real SS.

Unfortunately that is not a 100% MUST . . My car does not have a R7T code, and I discussed with Dave H. that WU9 . "forced" the R7T . . which the purchasing dealer must have forgotten to check. . . .

So fun when there are "nuances" that make hard and fast rules not true . .

Ain't it fun trying to "discern" all the data? . . . I read the R7T thing and then looked at my car to find it did not have it . . . I was Like WTF? . . . But after chatting with Dave I was put at ease.

I'll tell you the even weirder thing. While all (I guess in this case, most) SSes had R7T, not all of them had WU9. I'm not sure what WU9 actually means... any idea? Is it like Y2Y meaning second sticker content?

Is it possible your sticker is just wrong? Can you PM me your VIN so I can check it out? I've actually been working on the '96-'97 SS section on my site the past week, so a look at your car's options from the factory might help me out.

Here's what CompNine's RPO lookup shows:
Option Code First Year Last Year Description
WU9 1976 1981 MOLDING,WINDOW REVEAL WDO R/MLDG(WU9)
WU9 1997 1997 SALES PKG ANNIVERSARY Z28 SS Z28 ANNIVERSARY(WU9)

Z4C is also the RPO for the '97 30th anniversary package, which was also available on "plain" Z28s, not just SSs. CompNine shows:

# of '97 Camaro Coupes w/ Z4C = 3299
w/ R7T = 2474
w/ WU9 = 802
w/ Z4C+R7T = 659
w/ Z4C+WU9 = 802
w/ R7T+WU9 = 659

:confused: Something doesn't seem to add up here. But then again, CompNine reports that R7T is "unknown" and WU8 was the RPO for '96-'97 SS (which I know is not correct).

Let's get down to serious business and see if we can solve this issue Xsta by putting our heads and information together...

Production records are full of problems, so this is going to take awhile to go through.

Let's compare some total 1997 production records.

Compnine has 57,810 '97s are in their system.
Camaro White Book says 60,202 were made.
Camarosource says 58,152 '97 Camaros were sold, but states that industry trade journals say 54,972 were produced for the US market. No record for other markets.

I'm not a data cruncher for GM and never have been, but I personally believe a lot of problems with calculations lie in percentages being used. You'd see things like "71.5% had automatic transmission" and people would apply that % to a total number and come up with an amount that could be off by several cars. Whose records are actually accurate? I don't know, but I like compnine's since it's based on VIN #s. I didn't used to like it, but I like it now. Cars that were not given VIN #s, which could be test cars that were never sold to the public and were crushed when they fulfilled their purpose are not included, so I feel their numbers to be as accurate as we'll ever get. Other issues could have messed with the numbers as well, which I'm not even going to attempt to get into at the moment.

Conclusion: none of the numbers actually match up and it's hard to know what's truly accurate.

Let's work on '97 30th Anniversary SSes now...

Here's the definitions I have:
Z4C = APPEARANCE PACKAGE 30TH ANNIVERSARY
WU9 = SALES PKG ANNIVERSARY Z28 SS
R7T = CONTROL SALES ITEM NO. 44 (Camaro White Book defines it as "SS Package (non-Chevrolet modification)")

I have a SLP Information Bulletin for the '96 (not '97) SS reproduced by a magazine called Camaro Enthusiast (September/October 1995 issue) and it says...

What specific Z28 options are required to order an SS?
1FP87/Z28 (hard-top and t-top coupe models)
1FP67/Z28 (convertible model)
QLC (245/50ZR 16 tires)
GU5 (only required on 4-speed equipped cars)
R7T (specifies SS package)
SS package cannot be ordered with Acceleration Slip Regulation - traction control - RPO NW9

Things might have changed for '97. I don't have that info. Wish I did so I could get some concrete evidence on what WU9 means rather than relying on a definition of it. I don't have much stuff from '97. Most of my physical collection is from '93-'96.

Here's a break-down, and why the Z4C, R7T, and WU9 stuff doesn't make sense. Cars with Z4C & R7T should equal the same number as WU9 theoretically if WU9 truly just means 30th Anniversary SS.

Coupes:
Z4C = 3,299
WU9 = 802
R7T = 2,474
R7T & Z4C = 659
R7T & Z4C & WU9 = 659
R7T & WU9 = 659
Z4C & WU9 = 802

Convertibles:
Z4C = 1,001
WU9 = 264
R7T = 476
R7T & Z4C = 240
R7T & Z4C & WU9 = 240
R7T & WU9 = 240
Z4C & WU9 = 264

Total:
Z4C = 4,300 (total 30th anniversary Z28s and SSes)
WU9 = 1,066 (total 'supposed' 30th anniversary SSes)
R7T = 2,950 (total SSes)
R7T & Z4C = 899 (total 30th anniversary SSes)
R7T & Z4C & WU9 = 899 (total 30th anniversary SSes)
R7T & WU9 = 899 (total 30th anniversary SSes)
Z4C & WU9 = 1,066 (total 'supposed' 30th anniversary SSes)

^^This data suggests that:
1) WU9 ALWAYS accompanied Z4C, (ex: there's not a red Camaro running around with WU9, every single one was white with orange stripes)
2) every single Z4C with R7T has WU9 as well. Why could this be? For '96, R7T was the ONLY code for SS. For non-anniversary edition cars (as far as I know) all '97 SSes have R7T.
3) Not every car with WU9 has R7T, in fact, 167 are like Xsta's and don't have it.
4) WU9 is not similar to the '98-'02 Y2Y code, which suggested second sticker content (optional exhaust and such). Why can't it be similar? Because there are more Z4C, WU9 cars than Z4C, WU9, R7T cars and R7T DEFINITELY means SS for '96-'97.

Okay. So. Let's compare to some published numbers. Published numbers in the past (especially on websites) have NOT always been accurate, but let's use them anyway.

Camaro White Book is the most reliable published source for the public, but it is still full of errors that I'm going to point out. The author wasn't much of a 4th gen fan. He liked 1st gens and it's obvious because he barely breaks anything down, and he either left errors or settled for errors in the 4th gen section. It says 4,533 Z4C were made. This number corresponds with the figure it says for White Leather and White Leather + Houndstooth if you add them up. White Leather was RPO 103, White + Houndstooth was RPO 10C. I'm going to include Z4C in the calculations below to make sure the interior colors are strictly 30th Anni cars and not other colored cars with white interiors (ex: a red Camaro with white leather).

Coupes:
103 = 2,242
103 & Z4C = 2,242
10C = 1,057
10C & Z4C = 1,057

Convertibles:
103 = 726
103 & Z4C = 726
10C = 275
10C & Z4C = 275

Total:
103 = 2,968
10C = 1,332

If you add those two numbers up, you get 4,300, so as far as I'm concerned, Camaro White Book is wrong, and there were only 4,300 Z4C 30th Anniversary Camaros, and only 30th Anniversary models were able to get the white seats (though they were available for most exterior colors in '98 and '99).

Next...

Camaro White Book lists in the Addenda that there were 4,309 30th Anniversary ones... okay... their number changed... and it says that in their break down in this section, another 225 were built for the Canadian market. Well, that's close to true... The RPO code for Canadian equipment modifications is Z49.

Z29 Z4C coupes + Z29 Z4C convertibles = Total Canadian Z4C
145 + 79 = 224

224 of the 4,300 were Canadian. NOT an additional 224.

Next... Camaro White Book says there's 466 Z4C SS hardtops, 241 Z4C SS t-tops, and 251 Z4C convertibles. That totals 958.

Based on my numbers at the top, I got results of 1,066 (Z4C & WU9) or 899 (Z4C & WU9 & R7T).

Camaro White Book disagrees with my calculations again.

SLP had a break out of their records, and surprisingly, I discovered I have this. They did NOT separate the 30th Anniversary cars in their statistics according to a sentence on it, so this isn't all that useful at all. It states 3,038 SSes we made in 1997. That number is way off of what my totals above say and what Camaro White Book says.

SLP says 3,038 SSes
CWB says 3,137 SSes
Compnine says 2,950 SSes

A difference of about 100 between each other.

If I recalculate my numbers and include those WU9 Anniversary SSes that did NOT have R7T, we can get these numbers:

For reference, the math formula would be:
(R7T without WU9) + (R7T with WU9) + (WU9 without R7T) = SS
simplified to R7T + (WU9 without R7T) = SS

Coupe:
WU9 lacking R7T = 143
R7T = 2,474

Convertible:
WU9 lacking R7T = 24
R7T = 476

Total:
WU9 lacking R7T = 167
R7T = 2,950
Potential total SSes = 3,117

Soooooooooooooooooooo, what can we conclude from that?
1) SLP's records, which should be accurate, are actually reporting 79 fewer SSes than actually exist according to compnine's VIN database.
2) Camaro White Book is reporting exactly 20 more than in that database, if you include what seems to be the only two possible ways to end up with an SS (R7T and WU9 cars without R7T = all SSes)
3) Those WU9 cars that lack R7T really are SSes

That took forever. Thoughts? Anybody have any articles, press releases, or similar to back up or refute my claims?

I left a gap in my previous post.

SO HOW MANY 30TH ANNIVERSARY CAMARO SSES WERE MADE?!

That would be these numbers added together:

coupe:
Z4C and WU9 without R7T = 143
Z4C and R7T = 659

convertible:
Z4C and WU9 without R7T = 24
Z4C and R7T = 240

Total:
Z4C and WU9 without R7T = 167
Z4C and R7T = 899

Total 30th Anniversary Camaro SSes = 1,066

Of those 1,066 there were 110 LT4 cars. All were hard tops and had some other limiting options I don't feel like going through right now. I'll go through it on my website at a later date. What I will say is that 106 of those were production ones, 1 was a prototype, 1 was a development car, 1 was a race car, and 1 was immediately wrecked at Young Chevrolet in Dallas, TX and isn't considered part of the production because it was a total loss from what I heard. 6 were Canadian, 100 were American, and then there's the 3 early cars, and the one that no longer exists.

I don't know how many currently exist. It'd be interesting to know since the LT4 Camaros are likely going to be some of the most valuable 4th gens in the future, if not THE most valuable.

If anybody would like to share stories or pictures of these 110 cars, particularly the prototype, development car, race car, or wrecked car, I'd love to see them and potentially include them on my 4th Generation Camaro History site when I'm ready to do the article.

If anybody reading this is still in college, it'd be interesting if you could take advantage of your library's online resources (AKA their expensive subscription to them) and see if you can find a news article from '96 or '97 about the LT4 Camaro being crashed in Dallas, that'd be really neat to share. Some of the databases of old news articles I used to search in college are called LexisNexis, Infotrac, and Academic OneFile. There may have been others. Sometimes they have the text typed up, or even better, black and white scans of the actual articles.

Wow . my head is spinning! . what a lot of numbers to crunch . . .

But interesting info needless to say . . but you are correct it is VERY hard to find the cut and dry "correct" answers . . .

Some of my opinions . .

WU9 is the same as WU8 . . . they = SS. Period. . . the 9 just separates the 30th Anniversary SS from a "base" SS . . . so on the codes a WU9 must have a Z4C (USA) in the list . . I think that is a must and firm answer. . .

R7A and R7T were codes for SLP "stuff" . . . but what exactly I am not sure.

After purchasing my Hendrick LT4 . . I wanted to compile some of the data I received and here is what I compiled:

History of the 1997 30th Anniversary Camaro

1997 marked the 30th year of production of the Camaro, and Chevrolet wanted to commemorate this prestigious anniversary with a unique appearance package for the Camaro. The color pallet for the anniversary package was taken from the 1969 Camaro SS that Paced the Indianapolis 500 race of that year. An unmistakable color combo of white with hugger orange stripes and a white leather interior with houndstooth seat inserts. The interior was further embellished with 30th Anniversary logos embroidered into the front seat head rests, in the center of the rear seat back and on the front floor mats. Chevrolet offered this appearance package on the Camaro Z28 and the Camaro SS.

30th Anniversary Camaro SS

For the 1997 model year there were only 957 30th Anniversary Camaro SS’s built. Chevrolet designated the RPO code of Z4C to the 30th Anniversary Appearance Package.

The Introduction to the 1997 30th Anniversary Camaro LT4 SS

To further celebrate Camaro’s 30th Anniversary, SLP offered to its top dealerships an invitation to order what would become one of the most unique fourth generation Camaro’s ever built: A special content Camaro SS with a 330 horsepower, LT4 Grand Sport Corvette Engine.

Only 106 special 1997 Camaro SS 30th Anniversary LT4’s would be built. 100 would be for sale in the United States and 6 would be sold throughout Canada. Due to timing constraints for certification, the cars were not available for sale in California, New York or Massachusetts.

To purchase one of these special Camaro SS’s one needed to complete a SLP Sales Agreement Form and place a $5,000 deposit with their dealer. Once the deposit was received by SLP, the owner is notified of a production date. The first 50 cars were built between January and February 1997 and the second group of 50 cars was produced between March and April. Production date on HMS #5 was 3/26/1997

The Camaro 30th Anniversary LT4 SS required the following options from Chevrolet:

• Hard Top
• 1SJ - Z28 Preferred Equipment Group #2
• Z4C - 30th Anniversary Package
• WU9 - SS Package
• AG1 - 6-way Power Driver's Seat

The LT4 SS included all of the base Camaro SS options listed previously and added the following:

SLP LT4 Alterations:

• Second Sticker MSRP of $17,023.00 - On top of the Camaro sticker price
• 330 Horsepower LT4 Engine
• 330 Horsepower Tail Panel Decal
• Performance Exhaust System with Twin Dual Polished Tips
• Stainless Steel Exhaust Manifolds

SLP could have installed the impressive LT4 crate engines directly into the Camaro SS as is, but they took it a step further. All 106 of the production LT4 engines were completely disassembled, balanced, blueprinted and honed with stress plates. Areas of the engine that were checked and adjusted included, the deck, line bore, bearing clearances, head surfaces and a multi angle valve job.

One in 5 engines was selected to be tested on a Superflow engine dynamometer, and if your engine was chosen, the performance sheets were included with the paperwork inside the car. My LT4 Camaro’s engine was chosen for a bench test and the dyno sheet indicated a maximum of 333 horsepower and 344 lb/ft of torque.

Every LT4 Camaro was tested on a chassis dynamometer in addition to performing a short six mile road test, the dyno results were also included with the car and a letter was sent to each purchaser to let them know this testing would be performed on their Camaro. The provided sheets with my LT4 Camaro showed an achieved 281 rear wheel horsepower and 311 lb/ft of torque.

The Introduction to the Hendrick Motorsports Special Edition Camaro LT4 SS

While SLP Engineering performed the LT4 SS upfits they worked with Hendrick Motorsports to take handfull of the 100 LT4 SS designated for sale in the United States and make them just that more unique.

Hendrick placed an advertisement for their special Camaro in the April 1997 Hemmings Motor News publication.

• There are a total of nine Hendrick Motorsports Special Edition Camaro LT4 SS's.
• The 1997 30th Anniversary Camaro LT4 SS's are SLP car #'s 1, 3, 4, 5, 6, 16, 23, 43 and 71 of the 100.
• The #1 LT4 SS was Rick Hendrick's personal car (I believe this car is now in possession of Jim Perkins, former GM General Manager, and the current COO of the Hendrick Companys).
• MSRP was $47,250 - I believe they all sold for over $50,000.
• Changes to the car are mostly appearance
• Embroidered Hendrick LT4 Floor Mats
• Hendrick LT4 Dash Plaque
• Hendrick Key Fob
• Hendrick LT4 & SS Car Cover
• Hendrick LT4 Special Edition Sail Panel Badges
• Performance Exhaust System with Twin Dual Polished Tips
• Level III Sport Suspension
• Came with a short video of them being built at SLP
• Each car was provided with a signed Certificate of Autheniticty

The Hendrick Autogroup owns eight Chevrolet dealerships so each dealership sold one of the HMS Camaros to the public. The dealerships are: City Chevrolet, Rick Hendrick Chevrolet (Durham, NC), Hendrick Automall, Performance Chevrolet, Colonial Chevrolet, Superior Chevrolet, Rick Hendrick Chevrolet (Charleston, SC) and Quality Automotive. My LT4 SS was originally sold from Performance Chevrolet.

HMS # 1 (LT4 SS # 1) Sold From: City Chevrolet Charlotte, NC
HMS # 2 (LT4 SS # 3) Sold From: City Chevrolet Charlotte, NC
HMS # 3 (LT4 SS # 4) Sold From: Rick Hendrick Chevrolet Durham, NC
HMS # 4 (LT4 SS # 5) Sold From: Hendrick Automall Cary, NC
HMS # 5 (LT4 SS # 6) Sold From: Performance Chevrolet Chapel Hill, NC
HMS # 6 (LT4 SS # 16) Sold From: Colonial Chevrolet Virgina Beach, VA
HMS # 7 (LT4 SS # 23) Sold From: Superior Chevrolet Merriam, KS
HMS # 8 (LT4 SS # 43) Sold From: Rick Hendrick Chevrolet Charleston, SC
HMS # 9 (LT4 SS # 71) Sold From: Quality Chevrolet Olathe, KS

Included with the purchase price of the car were travel arrangements and accommodations to pick up the car. The delivery of the nine HMS Camaro SS was to occur at the Charlotte National Speedway but unfortunately it was booked, so the gala affair was held on June 25, 1997 at Hendrick Motorsports Headquarters in Charlotte, North Carolina. The vehicles were arranged around the checkered flag “Winners Circle” center plaza and covered for unveiling by their new owners. Adjacent to the cars were Quaker State Duffle bags and a case of SynQuest Synthetic Motor Oil.

People on hand at the delivery:

• Rick Hendrick
• Jim Perkins; CEO Hendrick Motorsports and former Chevrolet General Manager
• Terry Labonte; #5
• Ray Evernham; Crew Chief
• Chuck Mac; HMS Designer
• Reg Harris; SLP Engineering
• Matt Murphy; SLP Engineering

The new car owners had photo opportunities with the people on hand and had lunch with Rick Hendrick and Terry Labonte.

Jeff Gordon; #24 and Ricky Craven; #25 unfortunately were not available on the actual day of delivery but they did arrive the following day. A few of the car owners had already left with their new cars, so only the new owners that had stayed around for the next day were able to meet them and have their cars signed, if so desired.

Other Info:

• Cars # 7 (SLP SS # 23) and # 9 (SLP SS # 71) are the only two Hendrick Motorsport Camaro SS’s have the optional all white leather, the other seven have the standard white leather with houndstooth inserts.
• The Hendricks crew did not like the exhaust, it was too quiet, but it could not be changed in time for delivery.
• The dual twin tip performance exhaust is interesting, it has extra resonators AFTER the muffler just before of the tail pipes.
• The cars were delivered with a case of Quaker State SynQuest Oil & other QS, stuff - which I currently do not have.
• HMS #4, #5 and #6 were sold to mutual friends from Utah, two have been resold, the other is still owned by the original purchaser.
• Car # 9 (SLP SS # 71) the owner had the outside of the hood signed and clear coated.
• I have made contact with only one other HMS owner #4 of 9.
• At time of the delivery the Hendrick LT4 SS car covers, dash plaque and exterior sail panel badging were not available, and were shipped to the owners at a later date. Cars were delivered with the standard Hendrick SS car cover, dash plaque and sail panel badges.

Breakdown of known RPO code options on the HMS Camaro LT4 SS’s:

HMS # 1 (LT4 SS # 1) Options: 10C,
HMS # 2 (LT4 SS # 3) Options: 10C, R1*
HMS # 3 (LT4 SS # 4) Options: 10C,
HMS # 4 (LT4 SS # 5) Options: 10C, UN0, C49, U1S
HMS # 5 (LT4 SS # 6) Options: 10C, UN0, C49, U1S, R1**
HMS # 6 (LT4 SS # 16) Options: 10C
HMS # 7 (LT4 SS # 23) Options: 10I, UN0
HMS # 8 (LT4 SS # 43) Options: 10C, R1*
HMS # 9 (LT4 SS # 71) Options: 10I

* SLP Additional Content of the R1 wheel and tire package
** The R1 package is indicated on the second sticker, although documented by HMS to be in error.

I own Hendrick Car #5, SLP LT4 SS #6. I cannot take the credit for this information. It has been compiled from information gathered from the documentation included with my LT4 SS, from the former LT4.com, other sources from the internet, friends, former and fellow LT4 SS owners.

WU9 is the same as WU8 . . . they = SS. Period. . . the 9 just separates the 30th Anniversary SS from a "base" SS . . . so on the codes a WU9 must have a Z4C (USA) in the list . . I think that is a must and firm answer. . .

R7A and R7T were codes for SLP "stuff" . . . but what exactly I am not sure.

I don't have time at the moment to go through things, but from what I could tell yesterday, if you want to get technical, you can't say WU9 is like WU8.

WU8 for the '98-02 SSes was like R7T, it's what all the SSes were supposed to have.

WU9 on the other hand was something only some of the 30th Anniversary Edition white and orange SSes had.

R7A isn't involved with SLP I don't think. I'd have to check tomorrow. I'll look into it; I don't remember what R7A is off the top of my head and I don't want to stick my foot in my mouth. :lol:

Your other posts I'll have to read tomorrow! :)

Okay, had a bit of time before a client meeting on the phone.

R7A definitely doesn't relate specifically to SS, because it was used years before the SS was even available. I checked it for '94 and over a 100,000 Camaros had R7A. In 1997, 44,915 of the 49,515 coupes had it, so it doesn't seem SLP related at all. Even 29,956 of those coupes were V6 coupes and they had R7A.

R7A literally means CONTROL SALES ITEM NO. 26

I have never found a guide to what these control sales item type codes mean. Deciphering them through a process of elimination is just about the only way (other than finding something old that says what they literally mean) and it takes forever, and sucks to do.

For the 1997 model year there were only 957 30th Anniversary Camaro SS’s built.

I'm going to attempt to figure out if that number is the number I calculated (1,066), just without the Canadian cars included.

coupe:
Z4C, Z49 and WU9 without R7T = 45 (of the 143)
Z4C, Z49 and R7T = 0

convertible:
Z4C, Z49 and WU9 without R7T = 24 (that's right, every single one of these was for Canada (check previous post's number)!)
Z4C, Z49 and R7T = 0

Total:
Z4C, Z49 and WU9 without R7T = 69
Z4C, Z49 and R7T = 0

Well, didn't quite get down to that number. According to my calculations, 997 were American (or not Canadian at least) and 69 were Canadian. I don't have the export RPO codes written down at the moment, so I can't check those to see if any were, for example, sent to Japan or Europe. I don't know where the number you have came from, but it seems too low. It might be one of those numbers based on percentage like I mentioned earlier.

305 horsepower LT1 V8 Engine ( 310 horsepower with Optional Exhaust )

Is this really accurate? The '96s were reported to have 300 hp with the Z28 exhaust, 305 with the Two On The Left exhaust. Was TOTL standard in '97 and they are referring to Dual-Dual as the optional one making 310 hp?

Do you have any documentation listing the SLP part numbers for the LT4 or LT1 SSes? I'd love a scan of it if you have anything. I have a very incomplete list.

Do you have the video of the LT4 SSes being built? Can you take a video using your digital camera on a tripod of the TV playing it?

Are you the original owner, or second owner of your car?

Do you happen to have a picture of the R1 tires option on anybody's car or unmounted? How were these wheels and tires delivered? Surely they weren't shoved into the interior of the car were they? I've seen people do that. Only 1 fits in the trunk, two in the backseat barely, and 1 in the front passenger seat.

What I was trying to say is ALL 30th Anniversary SS Z4C Cars had to have the WU9 to become a SS . . . at least that's what Dave told me one time . .

And that the WU9 "forces" the R7T whether it shows up on the list or not . . .

I am the 3rd owner of my car . . . never been titled still on MSO.

I do have the VHS video, and I have a novel of data that came with the car . . which is where a fair amount of the above listed info came from.

I do not recall where I got the power numbers.

I do know the Dual Dual Exhaust was an option in 1997.

As for the R1's I have no clue how they came . . . sure wish mine had them . . . but I assume Hendrick kept them, even though they are listed on my SLP extra content tag . . I do have a letter from Performance Chevy saying they were not included, and listed in error.

My LT-4 Has the code WU9 , Z4C , and R8T. The build number is 2436 that would suggest the 2nd build of the LT-4 cars. How to tell proof positive?? There are a lot of different "small" things to look for. For a while I was concerned that there would be "cloned" vehicle's out there but there is almost no way to copy every last detail on a Original car.
The best advice is to check on message boards like this one and you will be able to find out quickly if you have found a true LT-4 car.
I purchased my car from Dale Earnhardt Chevrolet and they thought that would be able to get more of them. But we know how that worked out.

Looks like it is LT4 #11.

10I - All white leather
UN0 - In Dash CD

R1 - BFG R1 Wheel and Tire package?

Looks like he sold one . . . May I ask are you the original owner?

Xsta, I just noticed this thread and I am surprised you own one of the 9 Hendricks cars. I also read that you only made contact with 1 owner of the other cars. I will find out more info but a family member of mine I believe he is the owner of #9. He talked about his hood being worth a lot and it would make sense if it was signed. He resides in orland so is very local to you considering there are only 9 made which is why it's surprising. Like I said, I will chime in more when I find out info and will also try to get pictures to share. He said he received a video with his car where a nascar driver took it around the track before it got put in the trailer. If you know names, I will PM you.

We are doing some research to determine the value of our 1997 Anniversary convertible SS SLP. This was very informative and a very good description of our car - down to being 1 of 6marketed in Canada - thank you! One thing I found confusing on the internet is one place said that there was only one M30 for the 1997 model. Ours has M30 RPO Code. Do you know if there is only one?

After purchasing my Hendrick LT4 . . I wanted to compile some of the data I received and here is what I compiled:

History of the 1997 30th Anniversary Camaro

1997 marked the 30th year of production of the Camaro, and Chevrolet wanted to commemorate this prestigious anniversary with a unique appearance package for the Camaro. The color pallet for the anniversary package was taken from the 1969 Camaro SS that Paced the Indianapolis 500 race of that year. An unmistakable color combo of white with hugger orange stripes and a white leather interior with houndstooth seat inserts. The interior was further embellished with 30th Anniversary logos embroidered into the front seat head rests, in the center of the rear seat back and on the front floor mats. Chevrolet offered this appearance package on the Camaro Z28 and the Camaro SS.

30th Anniversary Camaro SS

For the 1997 model year there were only 957 30th Anniversary Camaro SS’s built. Chevrolet designated the RPO code of Z4C to the 30th Anniversary Appearance Package. The 30th Anniversary Camaro SS also required the following RPO codes from Chevrolet; 1SJ (Z28 Preferred Equipment Group #2), WU9 and AG1 (6-way Power Driver's Seat) options for coupe and t-top models, and required 1SM, WU9 and AG1 for the convertibles.

I have recently traded my 2002 buell s3 thunderbolt for a ss Camaro 1997.
I later found out its a slp/ss called slp and gave them vin and they told me it was car #1089. I was so excited! I work at a chevy dealership in Oklahoma. I ran vin and checked rpo's and its truly and SS/SLP got stickers
in both doors and under hood. bike was worth 3750$ and now I find out this could be worth a lot more. I have fixed all little this wrong with it. and had a new paint job on it but didn't know before I painted it that it is what it is, luckly I painted it back the artic white but put the new Chevrolet pearl in it and blacked the top between back window and t tops with blue pearl. got a set of 07 Z06 wheels 18" and putting hockey sticks on it. I pinstriped the wheels red have got new style ss emblems red and and Gm emblem like on the doors of the new cars and a Lt1 badge on back.i will post pictures. so is this really 1 of 957 built?

If you go and change the paint and added other stuff does it matter if its a 1 of 957 built? Maybe I am not understanding the question.
