Jammer1, yes, we will be finishing the supports, once that section of floor to sides is welded, and you are correct, that is necessary structurally, as if not done, the body would be floppy and weak. I pushed the floor back for seating for the boys. I wanted real foot room for them in the back. I can move the seats back, and seep them low, and there will still be leg room. I give up a bit of cargo area, but we are planning a sliding drawer unit for the back. We will also be putting in expanded metal between the passenger compartment and the cargo area, in case of a roll over, so that everything stays where it should. I have 3 beat up CJ 7 tops right now. I plan to split two of them, and make a hard top to fit the beast. And I'll cut one into a safari style top, no sides, other than what's necessary to support it, and no back.
