I got a new steering mast bearing from Jim Carter and also the horn button retainer that apparently goes on top of it. From what I can tell the steering mast bearing goes in the steering column and is used as a race to house the bearing balls, otherwise why call it a bearing, right? Unfortunately there are no bearing balls in the package it came in. Am I right and are there supposed to be bearing balls in this race that get get held in place by the horn button retainer that sits of top of it and, if so, how many and what diameter of balls? I got this truck in pieces so I don't have what was originally in the top of the steering column. Thanks for any help.
