I'm going to use 1.5" round, 2" square, and 1 x 2" rectangular tubing. One of the major tie-ins to the stock chassis will be two 5/8" U bolts that will go around the torsion bar housing. Other points for pickup to the chassis will be frame rails I've fabricated that extend the length of the pan just below where all the bolts hold the body and pan together. This is 1x2" rectangular tubing with holes drilled into it to allow the use of Allen head bolts in the standard body/pan bolt locations. There will also be a crossbrace between the two frame rails that will be just about where the front of the stock rear seat extends. I'm going to mock the whole thing up in ABS plastic pipe, I'll take some pics then to get feedback from anyone who has a mind for this sort of thing.
