I have a 1982 CX500, have started the mod process by de-plasticing the front, next job was changing the tyres for scrambler type dual purpose....... Went to put rear wheel back on and appears I've mislaid a spacer, axel goes through non-drive rear arm, then tapered spacer then brake hub, wheel drive side nut & split pin, only it appears as though there should be another spacer on the non drive side, anyone with a standard CX care to measure the distance between the rear arm and hub to put me straight?
