Not a simple bolt on. Also you would have a 6 lug front axle and an 8 lug rear. The 59 3/4 ton brake parts could be used to upgrade the Huck brakes to bendix brakes. You would have to grab the backing plates, cylinders, drums, and possibly the hubs to do the swap on your existing front axle. the 1/2 ton parts won't do you much good. If you have a 42 or earlier 3/4 ton, the lug pattern would be 6 on 5.5 just like the 1/2 tons.
