You can look on Ebay. Sometimes people are selling complete assemblies. I know that I sold my original ones off my 1949 GMC because the P.O. had enlarged the holes in the fenders so much that they didn't fit anymore. Ended up buying '51 to '53 assemblies which were just a tad larger and they look very much like the originals. As the other posters stated, Rob at oldgmctrucks may have some. Another person you can try is Mother Trucker in AZ. That's where I bought my lights. Not cheap but he has a large supply of trucks and can probably take care of what you need.
