Thanks Josh!
The first link is the place I called. Just ordered one from ebay. 👍
Well, it appears I'm back to square one. The eBay seller doesn't have the item in stock and never shipped it. I think I might do some measuring and see if there's another full bearing set that would work.
Try Vintage Motion. They can help with the old Cat bearings
