It sounds like a pretty rough bed. Holes and dents can be handled relatively easily, but rust outs can be very challenging. What are your ultimate goals as to correctness? Fortunately, the gauge of the metal on those beds is very stout. Really depends on your skill level, and monetary limits. Repo panels are available, but I have never heard of any patch panels. Have you separated all the panel Pieces? I made all my own tools for the riveting required and would be happy to share what I did to solve the difficult problems. We can best advise you after seeing some good photos. I can make measurements for you. The most productive way to communicate your needs is to start a Photobucket account. Take a lot of photo's, put them on the photo hosting site with arrows and other markings to define what you need. I have done this with others on projects and it works very efficiently. PM me if you want to start a dialog.
