The original mounts should still be there, the body lift pucks go on top of them. You will need a floor jack, some blocks of wood, and whatever size socket the body mount bolts take (3/4"?). Probably wouldn't be a bad idea to get new hardware too. I believe you will have to remove the front bumper also, maybe the rear too. Loosen all the bolts, jack up the body and remove the lift pucks. lower the body and install bolt. Work your way around the truck untill you have all of them removed. Then go through and tighten down the bolts. You might have to readjust the transmission/transfer case linkage. If you disconect the linkage before you start...adjust as nesasary to re connect.
