I have always used rebuilt clotches from a local shop. Never a problem. I have only replaced one that wasn't due to pulling my engine or tranny. ( I always do that during this time since it's out anyway and there isn't too much of a cost involved) That one was due to sorry carb and not enough gear. I am sure you know, but make sure to do a complete job. Clutch, pressure plate, release bearing, and have your flywheel surfaced.
