wouldn't it be enough to use regular washers with the right hole diameter?
Depends what the face of you crank looks like. Many are rebated where the pedal axle shoulder abuts the crank, so the OD of the washer needs to fit in that rebate.
Internet says that the crank (Sugino 75) is flat but I'll check again later. Thanks!
