This came out of my 65 Sportwagon. It's glass. See photos of the imperfections. The chrome ring isn't perfect. I circled the small ding. Scuffs and a small rust spot on the edge. $25 shipped from 60586 in the lower 48 US states.
That's a rare piece. But I'm sure I do but it's in a box somewhere in the garage. Unfortunately I can't get to those boxes. I have 2 immobile cars in the way.
65GSConv4sp was inquiring for me. I am looking for just the lens for the rear curtesy light that is above the rear window. Interested if you have the lens and picture, please. Loren
