Default 3rd gen rear axles

does anyone know if any 3rd gen camaro/firebird/ta came with a 12 bolt rear end, or the 8.5" rear housing i believe it is?? if so, what years? i would assume they put the 12 bolt in cars with the v8 options, but i dont know for sure

No 3rd gen car came stock from the factory with any of the above qutoed rears.,,,NONE.
Only stock rears were 9-bolt , 10-bolt and a very few Dana 44. No matter if it was a V6 or V8 it came with the same rear (except for gear ratios).

There were early 8.5 10 bolt rears but I think in the third gens there was only the 7.5, 7.62 and the 7.75 Borg-Warner. And of course the Dana originaly for the 89 20th anniversary turbo T/A's

Well if you have a extra $2000/2600 laying around you can buy aftermarket 9" Ford or 12-Bolt rear that will fit a 3rd gen car without too many problems[sm=headbang.gif]. Otherwise your SOL with any othert rear axle assembly/

yeah, the only issue i have with a 9" or other gm axle housings is the fact that they dont have a mount built in for the torque arm, i may just reinforce the housing and pray lol

I think the more common one you could find and be the strongest is the Borg Warner. You can tell it with the 9 bolt cover and disc brakes

i'm not too worried about it anymore, currie enterprises makes a 9" axle housing kit that bolts into the 3rd gen f bodies, comes with axle shafts too, about 1200 bucks, so i think i'll go with that

Pound for pound, the 9 inch is pretty indestructable.
