You will need three 8', 4x4's B. One is cut in half. Engine and tranny are out and everything is disconnected. Start by putting one of the 4' 4x4's on the jack under the center of the body near the front. Jack it up until you have enough room to put one of the full length 4x4's from one side to the other. Lower body down to trap the 4x4 between the body and the frame. Do the same at the back. Have some cinder blocks stacked high enough so that when you get the 4x4's in place you can lift the body high enough to put the 4x4's on top of the cinder blocks and keep the frame detached.
