1963 Taillamps
 

Does anyone know a source for lens to housing gaskets? Ames has discontinued them and I haven’t found them anywhere else. I ended up making back up lamp gaskets out of some round silicon gaskets I found on Amazon. Tail lamps are a bit tougher.

I suppose those were that dense white foam gaskets. Maybe you can get a similar material from McMaster-Carr in Chicago and cut your own. I had to do that for my air duct to firewall gasket because I didn't want to reuse the old gasket. There are a number of different thickness and density, open or closed cell foam materials to choose from.
