Mr Thomas, the main reason I used a 79 axle is because thats what was available. They are hard as heck to get ahold of, in fact a buddy waited over a year to get one to upgrade his D44 in his ford. The spring pads worked out perfectly as to where I wanted to mount my hangers. My axles are the bigger nontapered,when they break I go with a set of Moser's. I drilled my hubs and put in 9/16 studs. I'm still doing research on transfer cases. I'm debuting between using my 2wd transmission(nv4500) and using a divorced transfer case, I looking into Profab brand, but still have some questions to be answered. My other option is to buy a whole truck at a salvage sale and use the manual trans and t. c out of it. But it's not every week that they come up... . I used a set of springs out of a 1ton chevy military truck and had an extra leaf added. The front sets about 1. 5 in higher than a stock 4wd. I used the stock steering from the ford, including pittman arm and track bar. Sorry about pics, maybe Santa will bring me a digital camera...
