I have a few cast iron bells from the 1963-1972 era. The bell will bolt directly to a SBC or an L6 from 1963 up to maybe the mid to late 80's. I just don't know when GM changed to a newer bolt pattern. Some bells have a center bore of 4 + 11/16". The others have a center bore of 5.125" IIRC. Your 1962 bell should have a hydraulic PS clutch fork and should have a 4 + 11/16" center bore. You should measure the diameter of the front bearing retainer just to be sure it's the same size as the bell bore. The input shaft should be 10 spline and the correct length.
