Is there a Mustang fuel sending unit that'll fit MavCom's? If so then which year, as I've seen about four different Mustang sending units to cover the model years between 65-73? I just dropped the tank out of the Sprint and besides the tank being half full of sediment, the sending unit is toast. Anyway my reason for wanting to know is that the Mustang units are available here in Canada, whereas the Mav units aren't, and I'd prefer to be able to go the Canadian route if possible.
