Can you tell me what the parts are for the axle on the right hand side of the bike . First axle shaft , next the the axle adjusting bracket/washer .On the inside of the frame I have a large spacer . Is there another spacer that fits in the oil seal ? I feel there should be a spacer there but mine is missing . Attached picture of the right hand side of my bike . If you know the part number that would be great . Thanks
