This 1955-1956 Chevy Heater Air Inlet Diverter "Flapper" Box Deluxe is an original used GM part. This is the unit that distributes the air from the heater to the vehicles interior. We media blast and put a coat of black primer on the part. The box will have a functioning flapper. Nothing broken or frozen.
