A friend of mine has a '78 Cordoba similar to mine, his fuel tank level sending unit doesn't work anymore. There is no supplier that he's been able to find that lists one. There is a reproduction company locally that sells one for up through '74 B-body though, and having compared Dad's '73 Charger SE to my Cordoba the similarities run deep. Would the early-seventies sending unit fit the late-seventies fuel tank?
