Just a thought couldn't maybe a 4X4 front hub assy with disk brakes be grafted onto the Big Bolt front axel.The older ones have sort of link pin type set up so without an axel shaft in the way you could run a the pin all the way through.You would then only have to run a bolt through the center of the hub with a Washer or metal disk and gasket to seal it up. There are some tall and not so wide 16 inch tires. These ars close to looking like a 7.50- 20 tire .So they would not change the apperance to much
Or if you know a good welder you could make a nice tube axel also useing pieces of the 4X4 front axel & hub this would be very east to do. The recivers for the front hubs are pressed into the axel tubes and welded so cut them off chuck them up in a lathe turn off the tube and weld .For a jig you would have already figured how long the tube has to be ,so you would bolt your spring pirches to the springs lay your tube accross center it and only tack the perches on.Then level the truck up side to side .Next you would have to a bar turned so it would fit down through the top and bottom pin holes on the hub reciver with enough extra so you could place that magnetic thing that you can check for angle (sorry forgot the word)next you would need your tires on the rims so you can set the height of the truck .Now you can tap the hub recivers into the tubes ,you would have turned them in the lathe so that they are snugg but if you heat them a little to turn them to set the caster once the caster is set tack them good .Now unbolt it from the truck put on a welders table clamp it down good tack a few baces on so it has no chance to move and weld that sucker up .Now you have disk brakes just an idea
