Dash Lens Set features highly polished clear injection molded lenses that have been reproduced to duplicate the originals exactly. Top-quality plastic and highly polished molds make them the clearest lenses on the market. All numbers and letters are recessed on the back side and painted white. Edges of the lenses are painted green to transmit color to the letters when backlit, just like Chevy produced them in 1955, 1956 and 1957. #300 will work on any 1957 Chevy model.
