So, in that light, yes and no.
During the 60s and early 70s most if not all mopar cranks were drilled and machined for the pilot bushings (adapters). I have even taken apart (believed to be virgin)engines from automatics that had the bushings installed! But even if the crank is not machined for the bushing, NAPA, here in N.America, makes a bushing for a drilled-but-not-machined crank. Furthermore, Chrysler now stocks a ball bearing pilot that uses the convertor register to do the piloting.
Do you have a part number for the napa pilot bushing, or the mopar needle bearing cup pilot bushing?
