Does anyone know where to get a good deal on Wiper motor brushes for a tr3 D2 motor? I heard I could purchase them at Ace rather than pay 22.00 for such a small item. They seem to be the same thickness as the generator brushes and I have some old ones of those around. I am trying to think of a good way to cut them down, perhaps a hacksaw or maybe grinding them down. I am not sure how long they are supposed to be either.
