Robb -
Excuse me for asking if you've answered it already: where are you located? It's a good idea to put it in your sig line so locals can offer better help.
You're be jumping off the deep end with a much-modified truck. Not that's bad, but can you swim? There are lots of advantages to bone-stock vehicles, like maintainability. If we accord Jason the respect all Mudders get

, then we'll assume that all the mods were done properly. But only he knows the details of each one & it would be difficult to join this saga without prior experience with at least an FJ40 or something with a similar drivetrain.
And Jason, you know full well that if you get 50 cents on the dollar for the upgraded parts alone (nothing for your labor), you'll be doing good. That's ignoring the "bigger fool theory" under which sports teams are sold. If you find someone that knows a lot about the vehicles, maybe you'll get close to what you want. Never know.
