This is the passenger side quarter window glass to roof seal molding from a 1956 Cadillac 2 door coupe. This will fit all 1955 - 1956 Cadillac 2 door models. This mounts to the roof, right under the drip rail, and the quarter window rolls up and into it. This piece is in very good condition. The felt seal really should be replaced, and the stainless could use a good cleaning and polish but there are no dents or other damage to it. Comes with the short extension piece as well, as shown. Sold As Is, As Shown. I have both sides for sale in the store.
