I would strongly venture that you need no new panels, just a good old-school body man. That chrome bumper bar is Hall Pantera aftermarket and would be nice to toss in the garbage.
I have thought, but since mine is still in great shape not yet done so - that coating the rear tub with a truck bedliner spray would be a very workable solution. Just something to consider.
Lots of advice here, and lots of info at the two sites listed in my signature below.
