I had one of the 12 Olds rears several years ago. One of the main differences I noticed is the Olds rear axles bolt in, just like the B-O-P 8.2 10 bolt whereas the 12 bolt Chevy, 10 bolt Chevy and corporate 8.5 axles are held in with c-clips. The Olds rearend parts are very hard to come by and very expensive, I once called on a set of 3.90 gears and the price was over $450 and this was for used parts. I pulled the rearend back out and put the stock unit back in my GTO.
