The axles came from a '91 diesel Suburban and the plan was to also swap-in the 4L80E/NP241, but never saw the need once I started driving it.
I don't what your use is with yours, but unless you can grab the best 700r4 for dirt cheap, I'd just rebuilt yours and roll with it.

It's just going to be a daily driver. I have my dually if I need to haul or pull anything.
