Rear end options?
Im near ready to modify/swap out the rear end in my 1969 Cutlass, car was born with a peg leg and gears that dont suit my driving style (2.73) or something like that, dont recall exactly anymore. Anyhow im wanting a posi and something in the 3.55 to 3.73 ratio range. Seems i recall modifying the existing rear end was cost prohibitive? Any options for a direct bolt in from another Olds or? Im running a BB and M21 close ratio drivetrain. Thanks for the help in advance.

I D Differentials
www.jdrace.com has a I D Differential or you can snap a few shots of the rear cover that will help us ID the rear. Jim

It should be the 12-bolt O-axle. Gears for these are about non-existent right now. I would build a 71-72 8.5" 10-bolt,or a 12-bolt Chevy. If you can't find anything out your way,I have both styles that I can build to suit.
