That's mainly it. I've come across some axles, but often they want the whole truck gone. Where I live I can't put it anywhere once the axles are off, and I have a thing against destroying parts lol. It's annyoying ironic though that I have to work things out to get parts from an hour away because my truck that could get the parts, needs the parts, lol.
I might have to just put in a gas engine for right now and do the Cummins later. I think something with EFI would be worth the effort, but finding a deal I can afford and get to work out is a bit tricky at the moment, lol.
