The outer skin, equivalent to the fender on the front. Its spot welded on the bed in the front back an top rail. I have one that had a run in with a bobcat bucket - standard bodywork aint gonna fix it. Its either a bed side or a whole new bed.
Has them. I checked out one for my truck and it was quoted at $270 plus shipping. Cool!!
