This is the Ranco heater control valve from a 1955 Cadillac. This will fit all 1955 Cadillac's, but please verify for yourself that it is correct for your application before buying. This mounts on the firewall of the car. This came from a non running parts car that sat for years, I have no way to test it and am selling it as is. The levers move and it is not seized or anything, I don't see anything wrong with it. Sold As Is, As Shown. Please let me know if you would like any other pictures of info. Thanks
