On the one ton the front panel doesn't attach to a cross member. It's just bolted to the two bed sides, with a long bolt that goes through the roll. The bed boards slide under the lip, which is the same height as the angle strips on the sides of the bed side. There are holes in the lip that line up with the last holes in the metal strips. I'll see if I have a photo that shows what I'm talking about.
The lip is actually two lips that make a sort of channel that the ends of the boards sit in. In the photo you can see that one of the boards is in place, and one of the metal strips is sitting on the lip.
Looking at photos of other trucks I think the front panel is unique to the one tons.
I hope that makes sense.

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 ( https://timwhiteblues.imgur.com/ ). I live way back in the woods in the Ozarks on 40 acres at the end of a 2 1/2 mile private road.
