Ed, you are correct it is a plastic part and I have not been able to find any nos. These are not too bad in all honesty. What I was hoping to track down was gaskets for them.
Paul, what vendors are out there that chrome parts anymore. I know the small job shops have closed here and become EPA Supersites, lol
Was able to track down the part number and are from ‘72 DeVille headlights.
Paul, so how do plastic parts get that chrome look?
