What's the pattern on the front hubs? That should be the deciding factor.

Finding a 5 on 5 rear axle with the right gears that will fit under the truck and not have the tires stick out too far may be the big issue. Most are also going to mean that you have to come up with another driveshaft if you already have one.

A 71/72 GMC 1/2 ton rear would give you 5 on 5 and the least hassle mounting it. It might not be in the way too wide category.

Another choice and probably not expensive might be a rear out of an early 80' full size Buick Electra, Olds 98 or Chev Caprice that had an overdrive trans. I think they had 3.5 or 3.7 gears. You have to make sure and check the bolt pattern and make sure the donor was an overdrive car. The width on those is probably close to spot on but they have a lot of scabs you will have to trim off.
