Dont beat me up for asking this question but after reading and researching I still cannot figure this out. My 99 trans am looks like it has a formula spoiler or hatch on it? I ran the VIN # on compnine and figured out that it is a TA and it has an Rpo code of T48 spoiler? I understand that there is a possibility that a previous owner replaced the hatch on it with a non high rise formula one, but I don't know that for sure so was this car ordered with this hatch/spoiler on it or was it a replacement?

I will have to post a picture later when I get home but I am sure you get te idea.

 

SLP had a few spoiler options. It's hard telling without a pic though.

 

 

Looks like a firebird (V6).In the pic it doesnt have the T/A rear bumper and looks like it says firebird between the tail lights.

 

It's definitely a TA it's a ls1 6 speed I just can't figure out if one would ever come factory like that or if someone changed the hatch and or rear bumper. That's not the best picture it's all I had on my phone. Here is the compnine report.

its a formula with a ws6 hood on it according to your rpo codes. not a trans am.

 

I dont think that there was an option for spoilers, only way a T/A got that spoiler is if it was on a convertible. Could have been in an accident and replaced

Could you post up some better pics of your car

 

That car is a formula.

 

I will have to post some more pics when I can this weekend. So your thinking there isn't any way that it came this way? The rpo code Y82 trans am package base which means it is a TA so I guess I am more curious to know if there was anyway possible that it could've come stock this way? I will get some more pics up when I can. Thanks for the replys, I've read alot of threads and forums trying to get to the bottom of this. Thanks again!!

 

actually the spoiler was RPO T43 and was optional on the 94-95 LT1 cars (i believe all 93's had it.) I believe it became standard on the LS1 cars or in 96 or 97 on the LT1 cars

I'd say it was a trans am that got hit in the rear and they replaced all the parts with firebird parts (center filler panel, rear bumper, hatch) it does have the side GFX. what does the front look like?

If it has RPO Y82 it is a trans am though.

 

Looks like a Formula.

And convertibles only came with the Firebird low rise spoiler.

 

WS9 - MODEL CONVERSION FORMULA(MERCHANDISING OPTION) FORMULA(WS9)

That says it all: Formula. But I do agree it looks like it has side ground effects. What about a pic of the front?

 

IIRC All T/A's are formulas (WS9) and then those that are turned into T/A's have Y82 which he says he has.

 

Right, my T/A has both codes (like it should).

 

OP. if the front of your car looks like this.. then you have a trans am with a formula bumper and spoiler (same as firebirds)



if it looks like this you have a formula (or a trans am converted to a formula)

 

Here are some more pictures of the car.

 

Maybe the previous owner didn't like the original trans am rear so he put a v6/formula rear on it?

 

Guess I will have to start pricing some, I would like to put a TA bumper and hatch back on it. I will probablyl get a hood while I am at it and just have the whole car painted at once. So I guess that answers my questions someone has changed them out at some point. Since it didn't come from GM like that. Thanks for all of the input.
