Hi to all. I need a couple of pulleys for my David Bradley Super Power. The main pulley sandwiched between the clutch discs (#6271M1, aluminum) is broken, and the pulley on the sickle bar clutch has a crack in it, so my restoration is basically dead in the water. Can anybody help me out with this, or refer me to some place where I can get them? Of course, there was one on eBay last week, but I brought the tractor home after that and didn't know I would be needing any. Just wondering....was there ever a subsequent retrofit to a steel pulley? I haven't been able to find out one way or another. This one has the nicest original hood I've ever seen, short of a restored hood. Thanks for reading and for the help if you can.
