Hey all, I've been trying my hand at bodywork on my truck. Anyway, this past weekend I pulled my windshield because I saw a bit of rust pitting around the edges of the seal. Well, after running around the edge of the windshield frame with a wire wheel, I'm stuck with this:

It's my understanding that there is no patch panel currently being made for this area. That picture doesn't show all the rust; in all I'd say at least 50% of the bottom of the windshield frame needs to be replaced. Any tips for making my own patch panel or am I better off trying to find a section of good metal from a donor cab?
