I have a stock 69 camaro with a 10 bolt, 2.73 open rear end, not sure what size. I have a friend with a an 4.10 posi 8.5 inch 10 bolt set up and was wondering if they are interchangeable. What size ring gear came in the 69 10 bolts, are the housings different between 7.5 and 8.5 10 bolts. Any info would be great. Thanks very much.
Yours is an 8.2 inch. You should see what your friends 8.5 inch is out of. If it's a Nova or the cousin of a Nova then it'll bolt up no problem. And yes - the housings are different between all 3 sizes. Jon
