This high quality parking/turn signal shell has been used many ways. Made of die cast zinc, with patience it can be reshaped to fit any number of headlights. This is possible because only the glass lens is gasketed, not the entire shell. If you have a pair of original 682-J headlights, these shells will convert them to 682-C’s. Minimal contouring will fit them to ’35-’36 Ford headlights for example. This product will NOT serve as a replacement for the sheet metal stamped 682-C headlight part. The original part sat into an indentation on top of the headlight – when we designed our new 682 bucket, we did not add this indentation. Because of this, our shell has a different radius. If you filled or removed the indentation, our part would fit just fine. The shell is secured to the headlight with 2 #10 screws (provided) from underneath.
