Looks to be in good shape for a wheeling rig. Want to trade sheet metal??? I am almost certain by the picture you could use a new set of coil. I got some from Car Quest for 120 or so. Sounds like you have a pretty solid plan. Just be sure the ZF-5 does not come from a 460 or diesel.
This is from the last time I was at Twisted. I used to have a poser shot flex out on a deck over equipment trailer. It drove onto the deck and kept the other three planted pretty well. I mostly have trouble with the rear bumper getting hung up on rocks.
