The Hood... I think if it were me I would be looking for a new one. That rust there looks like it rusted from the back side inner hood to the out side. I would think it would be really hard to cut that out and fix. I would scrap the hood if it is rusted in the front like that. Most of the ones I see that are rusted there usually has a lot of problems else where. I would look in the junk yard and see if you can find a better one.
The doors to me look like you could cut those spots out and wield some new patches in. I have seen others do it and I am a couple weeks away from it myself. Once you get it cut out I would clean it good ( + scuff) and spray some Zero Rust into the inside of the door. Oh. That place where the door opened up too far, I guess you know to make sure to fix the door stop to keep that from reoccurring. I took the door apart on a 1960 dump truck and used a short handled hammer to knock the door crease.
I think the photos of the rocker panel and cab panel look to me to have some rust under the paint. Those are spots that are prone to rust on these trucks. If you doing the entire truck you could media blast that and fix what needs.
Everyone has always said in most of the posts I have read to only repair the parts of the panel or patch that need it. Don’t fit the truck the to the repair panel. Only cut out what you need to and fit the patch to the area cut out.
Sorry for the long winded response… I hope that helps.
