     The standard trans that came in the truck is a sm465, 4 speed with 1st gear being granny low.  Most people opt. to go with the nv4500 because of the 5 speed and overdive.
     There are several threads on here with those options, look in engine/drivetrain and search nv4500, or sm465.

Pretty straight forward. Just find a donor truck from about the same year as yours, and swap everything out.

Everything interchanges pretty easily, especially if you find a similar year. If you have the whole donor truck you can get the tranny, t-case, shifters, clutch/brake pedal assembly, steering column, clutch linkage, and driveshafts.

You will have to fab at least one hole for the clutch linkage to go through the floorboard, but on those older trucks the floor board is dimpled where the holes need to be. Also depending on the donor, you can just swap out the center hump in the floorboard that already has the hole cut for the 4-speed shifter.

You should also already have the holes in the frame so that the clutch linkage is a simple bolt up deal as well.

I'd look for an 85-87(91) truck with a stick, that'll net you hydraulic pedals as well. I don't think the 79 had the 203 factory, but I'm not 100% on that.

Thanks Alot Guys, I Just lost my job so this projects gotta wait.  The truck has changed alot recently, not so much, Good changes i guess.  The driver side i busted out All the bondo and sanded the whole thing down to metal.  The front fenders Shot,and the bed was bad enough that i took lumber i had and built a Wood flatbed.  Im gonna start something on here with pictures of all ive done with the truck so far, so hopefully youguys'll see it
