1957 Chevy Bel Air Sedan Complete Windshield Molding Trim RESTOREDThis 1957 Chevy Bel Air Hardtop Sedan Complete Windshield Molding Trim is an original GM part that has been professional restored to show quality. The difference between the hardtop and sedan is that the wiper arm cutout is larger on the sedan. The difference between the sedan and hardtop model is in the upper molding. The easiest way to distinguish between the two is that the sedan does not have a "dimple" stamped on the end closest to the center.
