My god man, I just looked at your pictures. That truck has patina alright. Are you sure you want to fix this one up? It must be easier to start with one a little less far gone.
I know I am spoiled but I don't think they make patch panels big enough for those holes.
It is a rare automatic and if it runs maybe a nice new cab and fenders etc would help. A nice parts truck maybe?
I know it can be done but that looks like a lotta work. Good luck with what you decide.
