dammit. I feel for you. Being the MORON I am, I tried to back my truck into the garage last night so the snow would melt off it. Of course, I did not clear off the side windows and backed right into the brick garage. Cracked and badly scratched rear bumper. Also scratched rear tail light cover. Like another poster said, you may be able to fix yours, and I would give that a try. Mine needs a replacement. I can only imagine how much this is gonna cost...
With the large amount of people doing bumper replacement here with an ARB or Shrockworks, I would bet you can find a replacement one on the cheap.
