This is the drivers side / LH door heat duct bracket from a 1958 Cadillac 4 door Sedan. This should fit all 1958 & 1957 4 door model Cadillac's, but please verify that it is correct for your application before purchasing it. This mounts in the drivers side door, behind the heat duct box, and routes the heat / vent air through the door. This does have some rust on it and should be sand blasted and painted before use again, but is otherwise in good shape. Good used parts that can be hard to find. Comes as shown, Sold As Is. Please let me know if you would like any other info. Thanks
