Well, a couple things to watch for the 79 and earlier used the passenger side diff and had the smaller 260 u-joints and around 82-84 they had vacuum disconnect axles. you will have a few problems to address. The lug pattern is 6 on 5.5 on a waggy. You can use early 70's chevy spindles and mid 70's to 85 ford hubs. To get a 5 on 5.5 pattern if you want 5 lug. But either way you need new rear axle shafts because there isn't enough material to redrill the larger pattern on the 8.8 flange. You can get six lug shafts made for the 8.8 if you wanted to go that route. The brackets can be costly but I believe tnt makes a killer truss you can order with brackets already welded on for a decent price. You should also way the pros and cons. Pros are serviceable bearings, lockout hubs, steering is up off the ground, thicker axle tubes , bigger tie rods, stronger ring & pinion and better selection of gears. Cons are it's heavy, low pinion so drive shaft is closer to the ground, stock inverted t steering has dead spots and overall hurts ground clearance.
