As Andy and I have said so many times - if it looks rough in pics, it's a scrapper. If it looks OK, it's rough, If it looks good, it might be passable with care. It it looks mint, it isn't. If it looks phenomenal then the pictures have been lifted from an old brochure.
Thing is that most of what you described is simple stuff and fixable. In fact you are going to get most of that on almost any 80 that you buy. Plan for a rebuild of brakes, steering, front axle etc. It's routine for a truck of this age. What hurts is the price. I would say in looking at 80s as long as you have skill on the tools, you want a tidy interior. Decent body panels, rust free tailgate and a chassis that is paint not rust nor globby underseal. Outside of that, a smooth quiet engine. All the rest is largely nuts and bolts.
Sorry it didn't work out. But keep looking at them. You build up a sort of memory bank. My advice used to be buy the first good one you see. Now it's buy the first reasonable one that you see.
