Any of the circle track racers' supply outfits like JEGS, Racer's Wholesale, etc. will have bolt-on front spindles for the "wide 5" full-floating front hubs, which are clones of Ford 3/4 ton rear axle load tubes. Those have been in use since the late 1940's or so to provide heavy duty hubs and bearings on round track race cars. I'm sure there are also disc brake systems made by Wilwood and others instead of the big drum brakes we used on the right front back in the 1970's. That's several orders of magnitude of overkill, but there's no need to reinvent the wheel when properly-engineered brake and bearing upgrades are available over the counter.

Just shooting off from this, but I seem to remember the 2x4 postal jeeps and vans using the same frame as a 4x4 and the same knuckles and attaching parts but just a solid tube with no pumpkin or lockouts.
Which should be pretty easy to take a set from a junk d44 chevy 3/4 ton and gaing ball joints, disk brakes, and much larger bearings in one shot. Only question is how much height will I gain with a straight axle vs the factory drop i beam axle?
