If nothing has been altered/welded/added that would interfere with the returning to the OE steering items mentioned then no problemo. Sway bars are good/recommended but there may or may not be interference issues. I would suggest getting it back to normal & have an up & running machine then check into a sway bar (type/dia/fitment etc) for your app. As you know the pitman arm bolts onto the st box splines/idler fits in the slot in the kmember/center link is by itself & the tie rod ends/sleeves on each end of the center link just drop into the tapered holes in the "arms" of the left/right lower ball joints. You would get the st box halfway between lock to lock & adj the sleeves so the tires are pointed straight ahead (that'd be a start).
