Im looking at getting a pair of AFCO double adjustable rear shocks, part no 3890M.

I measured the shocks in the car and the top shock bolt is 1/2in, and the shock mounting stud on the bottom plate is 11/16in.

Can anyone tell me if the AFCO 3890M shock has the correct top and bottom bearing sizes to bolt straight in to leaf spring 70 b-body?
