cab corners and rocker panels

[schurg]

I would have to say it depends on how extensive your repair is. if you are repairing the rocker and bottom of the corner I'd say you should be fine without bracing. if you have to cut well into the floor to replace the floor, floor braces, pillars, etc then you might want to brace it, especially if you intend to remove the body from the frame, brace it up good before removal, all should fit afterward
