Nice documentation of the drain hole locations.
It's the first thing I do when I get a "new to me" truck.
I typically use the rust conversion products on the inner cowl.
I spray it down and then pour some down into the areas I can't reach.
I avoid trucks with any evidence of rust showing at the top of the cowl from the motor side. I also peal back the windshield rubber, from the inside of the truck, to look for excessive rust there.
It's difficult enough to repair the areas I can get to like the floor and the cab corners. I am unwilling to go into the major areas when you can still find decent cabs if you look.
I know GM never intended these truck to last 60 years. However, for $5 extra they could have avoided a lot of issues with a little paint in the right areas.
