So for the torsion bars I can say they use the same piece. Just need to adjust the tension some although your truck looks like its been pretty close to maxed out. They don't normally ride that high from the factory, its already been adjusted. I'm curious to see how they fixed the camber at that height because I'm looking at a fully adjustable upper control arm from SPC to fix mine (93 dakota) I'd like it that high but there isn't enough adjustment in the control arm to bring camber back into a decent spec.
The radiator for the 3.9 and the 5.2 is the same part .
The fan shroud however is longer on the 3.9 because the engine is obviously shorter so you'll have to trim it back or remove it. This is easy if you going electric fan as you can just remove it. Going to an electric fan is a big benefit for low end power and something I plan on doing to my own soon, just make sure you get one that moves enough air to cool properly.
The AX15 is a pretty decent trans and will hold up to a non modified 5.2 just fine you could still do exhaust and a high flow throttle body for a little more OOMPH and it will hold. Any more then that and you'll probably need to upgrade to the NV3500. You will have issues finding a replacement or rebuild kit for that trans though. I lost 1-2 gear in mine (split my fork at the pin) and took me a year of searching (part time) before I found a place that would even look at one. Wish I could remember the name of the place....it was 5 years ago. Now I'll have to go look through my files when I get home.
Everything else it seems you have a handle on.
