I have been slowly putting this rear bumper together. I had to paint it so far to stop the rust. I am not sure what I am going to do yet with the rear side panels. I cut the rear cross member and welded the steel 2x4 directly to the frame rails. The first picture was my original sketch. Let me know what you think. Any ideas for side protection? I do not have a tube bender but I would like to do some loops on the sides with steel tubing.
