Vic,
I know the other day we had a discussion about your long bed to shortbed conversion. I had mentioned to you about me buying some of the lower rear patch panels for behind the wheel. I said to you that I had bought some patch panels that were made for a swb bed.. I was mistaken.. i believe i used the long bed ones and cut them down.. However with that said I did run across these on ebay. I am not sure the fitment and if it is what you would need but they do say they are for a SWB truck bed.
