Thanks Bill. You are right that the ball bearing numbered units mentioned are listed for both Chevy and GMC 3/4 tons. I did a pretty thorough web search and found none of the "roller style" replacement bearings (inner or outer) to fit 3/4 ton Chevy's or GMC's currently available. In fact I couldn't find a single cross reference to any roller style bearings for these applications. Just lots of the original style "ball bearing" units which seem to be pretty widely available.

Hope Bristol's Tree S is okay with using original style bearings as there doesn't seem to be an alternative out there. frown
