First, I apologize for starting a new thread. I thought I found the right size dustwashers at Arcadeshop Amusements, but the ones they carry are too big. The problem I'm having is that I'm using replacement .375" diameter shafts for Happ Perfect 360 sticks. The original shafts have a plastic sleeve that's .500" diameter, so the holes in the dustwashers that ship with the P360's are way too big for .375" shafts.
