Re: front body support, floor pan, etc When I cut the rockers off on my truck, the inner rocker was so far gone I could barely tell what was supposed to be where. From what I could tell the inner rocker and the front and rear pillars where one piece and welded to the rocker box. The front and rear cab supports where attached the inner rocker by the bolts you described. I decided that I can't repair the cab supports without taking out the rocker boxes. I just can't see being able to cut and weld in the new pieces without boogering them up with it in the way. What I plan to do is leave the rocker boxes off since they are the cause for the rust, and make something with some healthy square tubing to go in place of the inner rocker and tie the cab supports together. You will need something there because the rocker boxes are there for structural strength when the hard top is removed. You say you don't run a hard top but do you still have one? It would help things from shifting around if you bolt it back on before cutting anything away. Hope this helps a little.
