I can't seem to find the brushes to repair my 300td Blower motor. I went to a local auto electric place, and they said they can't get the brushes, same with ace hardware, grainger, and anyone else I can think of.

Does anyone have a part number or know of a source to get the brushes? I really need to get this wrapped up, and I can go to the junkyard to get one, but I don't have a way of testing it out.
