This is the Air Conditioning Air Dryer from a 1955 Cadillac. This will fit all 1955 Cadillac's that are equipped with Air Conditioning, and may fit other years as well but please make sure it will work for your application before purchasing it. This came off a non running car that had sat for years, it was all hooked up though. This is in good condition, and nothing looks to be broken on it. It has not been tested as there is no way to test it. I am selling it as is, as a core unit. Comes as shown, Sold As Is. Please let me know if you would like any other information. Thank you.
