I looked at the Mar K site, what I found were sort of generic instructions for a GM step side. What I'm really looking for are specific measurements for where the cross sills go. There are so many holes in the frame that I have no idea where they should be mounted.
I'm still a ways away from mounting things, I still need to strip and paint the bed sides, then order the $2000 worth of parts and get them painted. But I'll need to figure out where the pieces go. I like the idea of assembling it on the frame, but I don't know how that works. Do the cross sills get bolted down first? And do the bolts holding the cross sills interfere with the bed wood? Or do the cross sill bolts go through the bed wood? Do the bed sides bolt onto the end plates of the cross sills? And on the cross sills, which way is up?
As you can see, I'm pretty well lost on this part of my project. And it doesn't help that I have a rear bumper that bolts to the fenders in addition to the running boards. I'll post a photo of the rear bumper.

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.
