ok, nobody laugh, ok? i've got an SDN60 starter drive that i'd like to repair. yes, it goes on a boat anchor Prestolite starter, but the starter works and i already own it. those drives are about eighty bucks retail, but all that's wrong with this one is the itty bitty cup thingy that fits on the end of the small spring inside the drive is broken into pieces. anybody know where to get one? the little metal cup thingy, not the whole drive, not the whole starter. yes, i could probably find a buddy with a lathe and make one, but i don't know the material to make it out of and don't have the exact dimensions to make it to. so i ask.

thanks.
