I got mine when Shoson still had the parts. Now remaining parts are at Jon Sigur 225-445-6995 but I don't know what condition they may be in? (rusty?) The are standard bearings, I would take them down, check them for part numbers (they all had them) and then take them to NAPA to match. I had a number of them with all kinds of part numbers on them, the latest from China. I think you could even search on Ebay for them.
