Used parking light / turn signal bezel. It often has light pitting on the inside near the lens but otherwise has good chrome. The socket and bulb were tested and are good. Perfect choice for that all original low mile survivor that shows some patina. Mustang is different and the reproductions must be modified to work on the Cougar. 1968 plugs differ from 67 plugs in that 1967 has a bonded plastic fastener to the harness and 68 used a separate clip to keep the pigtail in place. Whereas PS and DS look similar they are in fact side specific, if you put them on the wrong side your light will show outward at an angle instead of straight on. New mounting pads and lens gaskets are sold separate.
Ford engineering number is printed on the wiring. C8WB-13234-B. Casting number on the chrome bezel reads C4ZB-13237-B
