After searching for a disc brake solution to the front axle fruitlessly for about two months today I broke down and ordered a fat man hub to hub subframe with stainless a arms, 12" chevy rotors and big calipers, power rack and pinion steering and the optional sway bar. I think I am back to using the mb diesel engine today too.
