This is the passenger side ( RH ) rear door steel arm rest core from a 1956 Cadillac Fleetwood. Please verify that it is correct for your application before buying. This was mounted on the passenger side rear door panel, it's the steel core piece that goes behind the upholstery to give it it's shape. It does have surface rust on it as you can see in the pictures, but it is still solid and would sand blast and paint up good. The molded foam rubber piece is still there and is in good used condition as well. These are common to rust out as they were never painted from the factory and if your door panel gets wet the moisture rusts them through. Good Used Original Parts. Sold As Is, As Shown. Please let me know if you would like any other pictures, I would be happy to e-mail them to you. Thanks
