Just wondering if someone could help me out. I am looking for a flywheel for a 400 motor for a 12" clutch. I know the manufacture number for it is D7TE 6375 B. Someone gave me a flywheel that is supposed to be for a 351M/400. The manufacture number is D7TE 6380 D. I can't find any information on this flywheel. Does anyone know anything about this flywheel?
