Can anyone get me the dimensions on the floorpan for a 47-54 Chevy truck? I'm wanting to get an idea of what the distance should be between the two A-pillars. My floor is a little warped so my driver's A-pillar is too far in. Since the rocker panels are strong enough to keep the door jam properly spaced, I should be able to reposition the A-pillar with a jack and a 2x4.
I think I'm going to end up doing this myself using 1x1 tubing for a subframe with 16ga sheet metal once I get the donor frame. Thinking of using 1x2 along the outside (to reinforce the rocker) and also across where the frame mounts would be. I think I might also drop the body an inch or two while I'm at it. I'm concerned with channeling too much since I don't want to lose legroom or have to relocate the gas tank. Also by doing it this way, I'm sure I'm getting into good metal on all the door pillars.
