Re: stock rear ends
they might exist, but goodluck finding them. Why the heck would you want to keep drum brakes?
You would have to find a non Y87 car that ended up with the 3.42 LSD. I'm pretty sure it would have to be in a 96 or 97 car. But I doubt the 3.42 LSD rear axle was available without disc brakes.

Y87 auto cars came with 3.42, LSD AND DISC BRAKES in the rear.
NO factory car came with 3.42, LSD and drums.Robert - owner www.FirebirdV6.com "Mid-life crisis? I'm way beyond that!"

From what I've heard, a disc brake conversion shouldn't be too bad.
The only difference is you will need to change the e-brake cable.

Re: stock rear ends
Originally posted by Black98FivespeedIf you're that worried about it, just replace the differential and the gears, and leave everything else the way it is.
To do a swap, just find the rear.
The only thing that will affect the ABS, is there is a ABS sensor on the top of the pumpkin. Its a little magnet that reads when a "reluctor ring" on the diff is spinning. As long as the reluctor ring, sensor, is all there you will be fine.
The rear I just bought, even came with the sensor in the pumkin, all I have to do is swap plug the connector in and my ABS will work.=
Important things on a rear swap.
1st, make sure its a 3-channel rear. There is a 3 channel and a 4 channel rear. This is an ABS thing. The 3 channel car has 3 abs sensors, 1 on each front wheel, and 1 on the top of the pumpkin. ALL V6s HAVE THIS. Next we have the 4 channel rear, which is traction control on V8s, not all have but it is an option. The sensors on are on all 4 wheels.
2nd, make sure it has LSD
All v8s and some V6s have it. The RPO code is G80
-older lt1s and some SS's come with an Auburn diff, its a clutch style diff, i think they are nicer but they are less reliable, and generally older since mostly found on Lt1s
-Most Ls1s came with Zexel Torsien LSD, which is a mechanical rear, more reliable.
3rd, Gears
RPO codes for gears(found on door, in glove, or center console)
GU6 = 3.42
Gu5 =3.23
Gu4 = 3.08
Gu3 = 2.73( I believe, you can double check the tech database.)
-Remember if you have an auto you will need to reprogram or you shift points will be off
-Also this will affect your speedo/odometer if you do not reprogram.
-4th, brakes
-Alot of rears will come with no brakes, you can swap your current brakes over if you want but a pain, and I hate working with drum brakes. If you swap your brakes you will need to pull the axles(not too hard) and undo the brakes and the brake lines. I did this once without even unhooking the brakes from my car, didn't have to bleed them or anything.
Or you can buy a plug and play rear for a 3 channel car, where you just hook it up, bleed it and go.
I have gotten a used z28 rear for as low as $100 and paid as much as $350.
$100 for a 3.42 lsd rear auburn 3 channel(ended up not trusting it so parted it out)
$150 for a 3.42 lsd rear auburn 4 channel(I tried to get it to work I did but a huge pain in the ***)
$FREE for a 2.73 lsd rear zexel, 4 channel
$350 for a 3.42 lsd rear auburn 3 channel all brakes and lines, even rear shocks (for my 3.4L, back in the day)
$250 for a 3.42 lsd rear zexel 3 chanel, out of a 2k2, with 10k miles. has Brakes, panard bar, lcas, shocks, pretty much everything. I got a reall good deal on this.
For what its worth the $350 one got ~100k while on my car and is still on the roads, I trashed all the others, and the $250 one is in my garage waiting to go in my car now(has the stocker I pulled out for another rear, but has auburn, and whines pretty bad, but still drives fine)
hope this helps.Last edited by DAS BOOT; 10-13-2007, 09:48 AM.
