I am pretty sure you will need to cut and reweld the spring mounts and sway bar mounts to make it fit. You might have to get a speacial U joint to make it fit. Make sure the the nose of the rear end is not any shorter or longer than the original or you may have to change your drive line. I put a 14 bolt semi floater 6 lug in my k1500 suburban. I got it on ebay for $600.
