I wouldn't put the time and money into building up that truck. It has tires, wheels, axles, and lift you're not gonna use anyway. And the body is falling off the frame. I'd sell it and find a stock one in better condition to build up. Keep the stepside bed if you want. Building a stock truck would be the same work, or maybe easier if there are things on yours that you'd want to undo or redo.

And seeing as you're gonna have to have someone else build it up, it's gonna cost some money. You can probably find one allready built for less than you'll spend to have it built up. Seems lots of people put a lot of money into these things and then don't use or don't like them and sell them at a big loss. Take advantage of that.
