I made a rear bumper out of some 1x3" C channel that I found out in back of the welding shop when the instructor told us to clean up. I used the band saw to bevel the corners and wrap it around a bid and then beveled the underside corner edges. I also made some sturdy new rear bumper brackets too with some scrap 2x3" box tubing I found laying around. This was all back in when I was in colleg in '95 and was installed on my old '88 toy. I wish I had some pics of it. It turned out pretty sweet. I used to back over small trees and rip them right out of the ground with it.
