I haven't, but have noticed that someone is selling a "kit" for adapting
such to fit a Stude truck on ebay. It should be an improvement over the old
straight axle, and I like it because it does not require cutting the frame
or welding. You will gain power rack & pinion, disc brakes, and independent
suspension with readily available parts. I imagine that unless different
rotors can be adapted, you will be using different wheels on the front,
though.
