@frank-giordano Frank, Check with the Filling Station. I believe they offer a conversion bearing. The Carbon bearing is the same for several years so I am assuming the same would be true for the ball bearing replacement.

I have Carbon bearings in all my old Chevys. I have never had a problem with them, EXCEPT when someone, who shall remain nameless, adjusted the bearing so that it was in constant contact with the plate. I have NOS carbon bearings and plates, if you should decide to go back original.

Thanks Mike, I will check to see if a sealed one is available. Maybe a slight adjustment will help.
