I don't know what metal the repair part comprises, but the part is out there for those who need it. How is the rest of the cab? Does it have anymore issues that you know of? How about the cab corners, kick panels, rockers, the extensions at the bottom of the door posts? If all of this is good, then it may be that you just need to belly up and get to work.

On my cab, we're going to have to cut the windshield posts in half, then cut the cab across the floor, from door sill to door sill and that's just to replace the firewall. Except for the posts, nothing will be visible to the unsuspecting eye.

A plasma cutter would be a great thing to have at your disposal, huh?

Check Tri-Pro Automotive. They're located in New Jersey, but they have all kinds of rust repair parts. There should also be someone closer to you than they are, but I don't know who it is. We have a vendor in your area, too. He (Wes) has all the answers to your many questions.
