A rear from a 4th gen will bolt right in. all the V8 models had disks and posi. You can find them for around $250 complete.Tracy

Ive got an LS1 rear in my 91 RS Camaro. They bolt right in, but your wheels will be pushed out about 1.5 inches on each side. Mine just barely fit under the wheel wells! I LOVE IT!No F-Body right nowComment

thanks guys. ive heard that when you put in a rear end you got to watch the pinion angle. that shouldnt be a prob with this huhComment

no worries. The torque arm will hold the correct pinion angle.Originally posted by Justifyedbyfaith
The only way you'd have to woory about pinion angle was if you had an aftermarket adjustable torque arm.Tracy

FYI the LS1s except the SLP cars have a Torsen not a limited slip (posi). I know it's technical but they are quite different.Originally posted by 88bird5spd
Also the spare tire in a LT1 car which is 15" will not fit over the brakes of a LS1 so I amagine a 3rd gen won't either.2002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning

I guess I didn't make my point clear enough. If you have 15" wheels, they won't fit over the brakes.Originally posted by 88bird5spd2002 Electron Blue Vette, 1SC, FE3/Z51, G92 3.15 gears, 308.9 RWHP 321.7 RWTQ (before any mods), SLP headers, Z06 exhaust, MSD Ignition Wires, AC Delco Iridium Spark Plugs, 160 t-stat, lots of ECM tuning

Even some 16" 3rd gen wheels wont fit. My 16" 91-92 anniversary wheels fit over the LS1 brakes.
Check the link below to see if your wheels will fit.

seems as if we kinda side tracked a bit. but it brings up another question. my car came with 14 inch wheels and from what i have been reading here they might not fit.
but i have a tendency to over think things. i got no prob puting 16's on but will that fit under the fender. i was thinking bout lifting the rear up a bit to give her a bit of a stance cause im going to put heaver strunts and spring under the front to acomadate for the added weight of the 350. and another question. do i buy a used 4th gen rear end or buy a brand new one. it dont make too much diff to me cept for the added cash.

thanks for the pic it gives me a finished look. about the iroc 16 well i didnt want to go back to factory wheels i persanaly hate those honey comeb looking wheels. havent put much thought into exactly what wheels i want but i do know that the 14'' weld raceing wheels that i got are gunna be changed out. but i got to get the rear end in first, wondering if the 14 s will work for a temp mock up. untill i find the ones i want. but right now i got lots of time to wait. (yeah for all the money going to christmas).
