I just saw some new ones (LEDs) in TRUCK BUILDER Mag. I think they were on the back cover (maybe). You can get stainless or primed. An ad for all kinds of Chevy lights. Don't remember which company.
I got a free '51 1-Ton panel that cost me $100 to have it towed to my place just to get a set of those little jewels ;~) Good rear fenders too, bonus!
