It's a pretty big job, but not impossible. Took maybe two weeks working at night a few nights a week. Shocks must be moved to behind the axle, brackets are added to LH spindle, a tab is welded to the frame to locate one box bolt, other holes drilled thru frame, steering column must be modded, and column must connected to box using new shaft/ujoints etc. Hoses must be located or made up, and a pump mounted to the engine.
