I have two AW-1 motor drives for the Nikon EL2. Each one could likely be restored to working order (I have stripped them down) except for one thing: The pesky nylon motor gear is cracked in each case.

Does anyone know of an active source for replacement gears that don't cost more than a drive is worth? The drives are not really worth much, and I don't want to pay over the odds for such a small plastic part. Any suggestions would be gratefully received.
