I'd put a Swepty front bumper on the rear. If I remember right I used Swepty rear brackets when I done it on a 73 Shorty about 20 years ago or so. You can weld a plate to a piece of square tube & mount it on top of the frame. Bolt a spare tire winch to it & get rid of the ugly factory hang down under piece. I was a Swepty-72-80 only for 31 years before I actually took a liking to the 81-93 7 years ago. Bob
