Ok I have a 70 Buick skylark and always assumed it had an 8.2 10 bolt rear end under it. Today I crawled under it and I believe I was wrong. After looking at the rear, see attached photo I believe it has a Chevy 12 bolt under it. Am I correct? I was going to look for the axle stamping but have no idea where to look. Can you identify this axle and give me a clue where to look for the stamping? Thanks.
