There is a bead of butyl rubber holding the channel to the metal pinch weld, no sealant in the glass channel (yet). I'm thinking of hitting it with my heat gun, then taping it down while it's soft and letting it set up that way.
I like the color, too! It's called Burgundy Maroon, and was only offered in 1953,

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur (
