I got a recent quote from a steel service center for material to make a rear bumper. I measured up and figured that if I cut one side off of a piece 6"x6"x.250 wall tubing, it would fit perfect over the rear cross member. Also had some .250" plate thrown in for quarter panel protection. I was shocked at how much it was....would you believe $887. Yes, that is just material. Evidently, all plate is the way to go. I didn't bother with the plate quote, I ordered a bumper.
