Another thought to consider John, you should have the corporate 8.5 10 bolt under your 1972 Cutlass. I read somewhere that GM used that rear end under lots of models including the 1/2 ton pickup and vans up to about 1989. That, supposedly you could pull the posi unit out of a van and have it installed in your Cutlass rear end. A little more work to do, but it may be easier to find that posi unit and have it shipped than the whole rear end. Joe, do you know if that's right?
