I am not 100% sure, but I do not think it will fit. I think the holes for the screws are at the wrong distance from the center of the gear, and or the gear has the wrong size hole in the center. I have a coulpe of the old Burns and I would think that the only place you might stand a chance of getting parts would be from e-bay. The parts are interchangeable with the USA-1 Nitro Crusher, so if you see parts for it they will fit the Burns.
