Installing some EBRs on a 1975 Puch Maxi. I was trying to salvage the lower bearing race shim from the old forks and it broke into a few deformed pieces. Treats appears to be out of the 7mm version so I’m SOL there and none of the other moped sites seem to have it. The steering tube needs about .35mm to firmly seat the race. Is there an off the shelf solution or something I can create to take up the slack?
