[Licensed to kill]

While i appreciate everyone that took the time to respond, I was actually only asking about lubrication of the ball, not how authentic the rubber ball is for a Model A or IF I should use the rubber ball. The car drove smooth as butter and straight down the road with the old rubber ball but the ball was torn and since i had it apart (to pull the engine/trans) I chose to replace the rubber ball and bolts. I decided to grease the inside and leave the outside dry.
