Its blacksheep10's design. I may be a little off but Im pretty sure this is the way Kelly said they did it they take rock side gears and turn them down to fit in the 14 bolt carrier then weld it all up. Draft the rock tubes onto the 14 bolt. Then they make adapter to use the 14 bolt spindles on the rock knuckles and they make custom drive flanges. They have to use wilwood calipers as its the only thing that will fit. I know there is alot more to it then that and im sure Kelly will chime in the give better details and fix whatever mistakes I made ;D Ben mindon runs this same axle in big booty Judy but it steers :afro: Maybe one day Heath will get his working :
