This is 1 x Drivers side / Left hand power window motor off a 1957 Cadillac. This will fit all models of 1955 - 1958 Cadillac. It will bolt right into 1955 - 1956 Cadillac's, but the wiring plug is different from year to year, so you may need to change the wiring in your car if you use it for a different year. I have bench tested this motor and it is in working condition, in both directions. It is a used original part and does have some rust on it. Sold As Is, As Shown.
