When you say "right side" are you talking about the passenger side? Its hard to tell in the picture above but this box looks to have been hit just above the wheel. The filler is deep and starting to break out. where its come off its also rusted. The drivers side looks pretty good but has a small rust spot at the front edge of the box about a half inch wide and three long. The floor has been cut out in the center for a fifth wheel hitch. I'm going to replace the box so if this would work as parts for you let me know.
