I been using the sealed bearing for years,picked it up from truck pullers, Mc Leod, I think sales them Jerico used to I know they have them for Chevrolets,I don't know what your application is.
Had some made before,can't remember bearing # make bushing to adapt OD to crank
BTW they fit in the bigger hole where converter pilot goes
Remember made one for Windsor in pulling truck once.
These bearings will last for years and if ever do go bad just go buy bearing and put in bushing.
