if its just a case of getting bearings that will fit the sierra bearing carrier and a different size driveshaft im sure you can get a different bearing. i use a company called LBK. they have never faild to get me bearings in the size i wanted.
if thats not the case i would be looking at machining/casting an upright with bearing carrier ways machined in the hub material effectivly making it all a single piece that the bearing races are pressed into.
