SO...can someone tell me what trucks would be an acceptable donor? I keep hearing Dodge had a lot of nv4500s, but then nothing else is going to bolt up. I'd like to have it as simple as possible ( because I am simple). I did see an early 90s Chevy parts truck with a 5 speed, but it was a half ton, and I didn't know if that was a 4500, or if the half tons had a different, wimpier tranny. I would really like to keep my existing transfer case if at all possible, but if I cant, then I cant.
How about length, is the 4500 longer or shorter than the th400? Can't do much without having to rebuild the front driveshaft, with the 6 inch lift I was told I'd have to lengthen it, but I didn't. It looks fine right now, but I'm sure it won't extend any further to reach if the standard is longer. Maybe the simplest thing would be to swap the trans and transfer together, along with it's crossmember, then just have two new driveshafts built. IDK.

Dodges also come with NV4500's but it won't fit a Chevy engine without adapters. T
NV4500 is shorter than a TH400.
$1000 is way too much for a used NV4500 unless it has been completely rebuilt. Sprags tend to go out on them and it'll grind shifting into 3rd gear.
The 1/2 ton Chevy trucks with manuals were probably NV3500's. Stay away from that transmission.
For a list of trucks that came with NV4500's, take a look here.

Hooking up the hydraulics for the clutch should be a lot easier than hoooking up all the mechanical linkages. You'll have to find a pedal assembly from a manual transmission truck.
