Well, maybe down south, that isn't an issue, but where I live (Minnesota), 1998-2002 Camaros and
Firebirds are VERY rare to be found. I'm lucky to find ONE in many a junkyard in the Twin Cities,
and by the time that I have found it, it has already been stripped pretty clean. The last two years
that GM made the Camaro/Firebird, they made very few of them, and by now, most of them have
been trashed, crashed, or simply worn out. If you can find one in your area for cheap, for parts,
you can make a LOT of money on it. Interior, chassis, trim, drivetrain, stereo, body parts, glass,
etc.

Z28tek, good rearends for those Camaros/Firebirds are actually becoming quite rare and hard to find.
If you find a good one, especially a "Z28" posi rear end "cheap", I suggest that you buy it, because
it will only go UP in value. There are NONE to be found in my area. In fact, I bought a complete
rear end (supposedly from a 2000 SS Camaro or Firebird) from someone in Nebraska a few years
ago. I think that I got it pretty cheap, especially since the seller said that it had relatively low miles
on it (looks like it) and it didn't cost me very much back then (about $400 including shipping).
I plan on using that rear diff (3.42 Torsen Posi) to upgrade my stock open 3.23 rear diff soon.
Unfortunately, that 7.5 ring gear rear end doesn't hold up to a lot of abuse, especially if you increase
the power of the engine noticeably. Some Camaro owners upgrade to an older 10-bolt or 12-bolt
rear end, which can handle more more abuse.

They both have over 120K.
You are right though, they are harder to find then I thought.
Usually even eBay has a bunch but I've only come across very few.

I have owned these cars for 12 years, so don't tell me that I don't know anything about these cars, especially
since I turn wrenches on them quite often.

Of the 16,845 V6 1998 Firebirds,3,895 had the Y87=23%
Of the 18,412 V6 1999 Firebirds,4,502 had the Y87=24%
Of the 14,678 V6 2000 Firebirds,3,128 had the Y87=21%
Of the 9,538 V6 2001 Firebirds,1,857 had the Y87=19%
of the 9,922 V6 2002 Firebirds,2,487 had the Y87=25%
1 out of 4 - 1 out of 5 had Y87,I don't consider that common.

It wasn't even a Y87 car, just a low mileage little old lady owned plain Jane Firebird. My 98 Camaro is a Y87 car and has the Auburn Limited slip in it from the factory.

This thread has gotten silly. Let me reiterate: all Y87 f-bodies had 3.42 limited slip differentials, whether manual or automatic, Torsen or Auburn depending on the year - the exact same rear end used on M6 LS1 cars. How do I know? We have had five of them in the family from 97-02, one manual and four automatics.
If you're looking at V6 car for a rear end, you have to verify the Y87 code. If you find it, you're golden.

anymore ( 10-bolt, 7.25 ring gear). I do have 3 torsen posi diffs in my garage, I intend to use one of them to upgrade my 2002 V6/5-speed Camaro with less than 34,000 miles, changing the rear gear from a 3.23 to a 3.42. I have a 2-series Torsen Posi for these rear ends to sell if you know anybody who is looking for one.

Of the 16,971 V6 2002 Camaros,2,411 had the Y 87=14%
1998-2002 Camaro and Firebird rear ends are identical,so a total of 35,937 came off the assembly line.

He's provided some solid and very accurate info in this thread, both recently AND 6 years ago. You revived this thread after six weeks to mention that very few, if any, V6 Camaros had left the factory with an LSD. But, in fact, many thousands were built in this configuration as shown by the stats.

I'm always relaxed ! Instead of guessing 'they made many' and/or 'they made very few', I posted the data available here on ls1tech.
