Yesterday ,when I purchased a differential gasket for my 66 American with 232 engine, they sold me a gasket for a round 12 bolt cover. Wrong! My 66 has the same differential as the 67 and up American. The cover is oval with 10 bolts. This is just an FYI when purchasing a diff. gasket at Advanced Auto Parts stores. They don't list the 10 bolt gasket for 1966 with ANY engine option.
