Bill, thanks for posting the link.
Dustman, if your damage looks like the truck in the link (more or less) I will be doing a metalshaping demo April 21st on fabricating the same panel as you need. I normally take a grunch of photos when I do anything so there should be a tech thread on the subject afterward. I plan on using basic shop tools in the hopes that it can be duplicated by most anyone without having to go buy any machinery for a one time fabrication. Hammers, home-made dolly's, perhaps a torch, etc.
