Sway bars are in! Thanks for the advice. They unbolted with no problem. there was no pew-load on either bar. Only problem I came across was a tab on the differential mounting location for the rear bar that served as some sort of register to keep the stock mount in place. I 'persuaded it' out of the way and the XII bushing retainer bolted right up!
After double checking my work, I took the X for a little spirited workout. The truck turns in much quicker now; very little body roll when making a hard corner. A couple of 'enthusiastic' laps around a traffic circle by my house showed the same noticeable decrease in body roll. So far, very impressed.
