I thought about wedges, but there is really no way to get in to remove them after installation. They would be blocked by either the curve of the frame brackets ot the lip of the running board. I measured the spacing of both the bolt holes in the running board brackets and the frame brackets, and both are the same at the outside edges. I would plan on tacking the bolts in about 1/2" in from the end position, which should give me an inch or so to play with.

Hopefully tomorrow I'll get one side done, and let you know how it works out.

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.
