Thanks guys for the nice remarks!! Sims, I'm not sure to be honest. When I replaced the marker lights, I simply put them back the way they were, LOL......By the way, these lights are great reproductions of the originals. They're made in cast aluminum with well made lenses. I bought them from NAPA. The originals were old NAPA cast aluminum as well, however the old castings had the NAPA logo. Thanks for watching!!
