Body lifts are in the 120 to 150 dollar range. The hardest part is geeting to all the body mount bolts. Don't go over 2" though. I had a 3" back in the day and it caused some wierd steering problems, but was fixed when I cut the lift blocks down to 1.5".
The install goes really quick, basicly, loosen all body mount bolts, detatch engine fan shroud, remove body bolts on one side, jack up body, install blocks and ne bolts, and repeat for the other side. Two hours tops.
