8.5" Rear end

[gharris79]

Hey guy's i'm looking to beef up my rear end in my Cutlass. I currently have a 7.5" posi from a IROC with 2:73 gears. I want to put a 8.5" in with 3:42 posi. What car should I be looking for to find a complete bolt in housing?

Thanks

The cars that got 8.5's were:
'84 Hurst/Olds
'85-'87 Olds 442's
'84-'87 Turbo Buick's (Grand National or Buick regal T type)
That's all.

Ok thanks. I can get my hands on a very rusty 85 442 so I may go get it.
