OK my bumper is home made from a piece of C channel. There isn't any plastic. But I'm not sure if I am getting great connection to the body. Ill drop the bumper and use a wire brush and make sure the 2 pieces are in good contact. I do know I painted the bumper before I put it on the Jeep so that might have something to do with it.but if that doesn't work ill have to look into a tail light mount.
