Got 4 packages of used parts in and they are looking pretty good, 2 hubs, 2 spindles, 2 upper and 2 lower A-arms and a box of MISC. hardware just waiting on the diff and the other box of MISC hardware. If only I could find an inexpensive rear frame section but I haven't seen one yet and making it from scratch may end up being better for this project anyway. Those boxes of MISC hardware are like gold when it comes time to find the right bolt.
This project will take me a while but I hope to get started fabricating it soon I need most of the major parts here and I need my P500 here at this house before I can really get into it pretty much in parts gathering mode right now.
Since I'll be using a front P500 diff in the addon with rear A-arms/spindles I'll have to play around with the axles I'll use, I want rear wheels on it and at the same width as stock but I think the front diff is wider than the rear diff so there may be a bit of searching for the right combination.
The power transfer is still going to be a piece of work but I'm not even going to worry about it until I get something somewhat built.
