the frames are totally different, and there is no "crossmember" in a 4wd to swap in. if you look under your truck, the big thick crossmember under the engine... the bottom needs cut out of it and the edges rolled in. took me maybe an hour to cut mine down, still haven't rolled the edges yet... too bad you're not working with a SCLB, i'd just sell you the whole frame, already cut, and mostly painted.
