Thats a good looking rig. Is it a 4cyl or V6? You might not need to swap in a 9" rear end. You could get a SR rear end with a locker in it and it would be strong enough, have disk brakes, bolt right in, and match the front ratio. Of course, if you already have the 9" and have a 4.56 third for it, then you're good to go in that regard.

Now, if your truck is a 4cyl, and in reasonable condition, lemme know. I might be eying some of your leftovers ;-)
