Model A's had the steel ball on the wishbone riding in a greased steel cup at the bottom of the bell housing and if they didn't get greased, the ball wore. The only recourse was to replace the wishbone or build it up with weld and grind it down. In '32 thru '48, they put a rubber ball (part #3446?) over the steel ball and that worked out quite well. The steel ball lasted quite well on all the car's I've seen. The rubber ball can easily be installed by lubing it up a bit, placing the large hole up against the steel ball and blowing a quick shot of compressed air into the small hole. It literally falls into place.
