You can probably get away with getting the control arms and Panhard rod, plus the springs, then add the mounting pad to the axle that's already in the truck. That would save some work and cost. Just took a look, there are a few sets of the trialing arms on ebay, right around the $200 mark, and it looks that the Panhard rod is available new for around $125. I also saw a tubuar set of of trialing arms, a bit pricey though.
