The frame horns are different between the 4 cyl frames and the 6 cylinder frames. The 6 cyl horn is wider than the 4 cyl horn. Almost 10 years ago I purchased an ARB winch bumper for a Gen I 4 cyl. I took the bumper and truck to a machine shop and they cut out the plate circled in [color:"red"] red [/color] and moved it toward the center about 1 inch. They then added a plate to the top and bottom to keep the box intact around the frame. The plate in [color:"yellow"] yellow [/color] does not move.
