Jack base does not go into spare tire

That is what I though might be the issue, but I was not aware that the B, C, E-body jack base has a larger diameter indexing plug on the jack base. If that is the issue then I just need to get a correct A-Body jack base. Maybe someone here has one that they could sell.

That's what I think is your issue. Yes the A body small bolt pattern jack assembly is unique and the base has a smaller diameter where the mast is located on the base allowing it to fit in the center of the wheels. Pictures would have been easier. Lol
