I swapped a lot of axles over the years. The very first Dana 60 I had went into an 84 3/4 that I picked up in MD. Had a 10 bolt front. I unbolted the 10 bolt, dragged it out of the way, bolted up the 60. Done. An 80s 10 bolt has the same brake line as a 60, at least the banjo fitting.

Also parted out many a 1 ton, and when I swapped another 84 I had from 1/2 to 3/4 ton, I had a front shaft from a 1 ton just in case. (swapped from auto to stick, used the stick parts off the 1 ton) Same everything.

Swapped 10 bolt and 14sf, both times a 14ff from a 3/4 ton bolted right up. Depending on year the E-brake cables will even hook up. I can't remember on the first 84, that was over 10 years ago, but I know the most recent 84 I had to have the rear shaft shortened.

Dually or single front axle will still bolt in, only difference is the wheel hubs. And I never swapped a master cylinder out either. Brakes and steering are the two areas where you NEVER skimp out on. I could lock all four up if I didn't mind kissing the windshield. If there was any issues I would have addressed it.

Half and 3/4 are basically the same thing, just different rears and heavier springs. Both have the 42 1/2" perch width. 1 ton has dimensions on the frame, but is thicker and taller. The spring hangers is where the difference comes in, so the perches on the axle are closer to the springs to clear duals, they are 40 1/2".

Hope this clears some stuff up for yah....
