A long shot l know, but has anyone an idea of which thread it is on the swingarm axle/nut on both the Mk1 bulliit ,and Mk1 super eight Santa cruzes.They are made of very light aluminiun ,and the axle faces have been peened over,making it very hard to screw on the alloy nut.What im after is cleaning up the threads on the axles with a nut of the same thread pitch.Im thinking its AF being american,but its a really coarse thread,and i imagine these original axles and nuts are impossible to find
