Welcome. Good way to spend your time. Truck is highly modified, which is not bad or good. Just make sure that is what you want. Some of the mods are what some of us do to make the truck more driver friendly. Disk brakes. 350 with auto transmission are added much later than the truck's original age. Parts are readily available at all of your auto parts stores. Looks like arms to the rear suspension are new.
Rust is in the usual places. Does not look like it is hidden, so likely you are seeing what you are getting. All pictured is repairable if you wanted to dress it up. It appears some body work, by way of bondo, has occurred during previous mods.
Look up under the top of windshield and along the windshield seal. Those places are hard to deal with and there may be some rust if typical. If rust there, water will get under the seal and continue degrade and water will come in. How do the cab perches look? Cab sits on 4 perches on the frame and I would want to know that they are sound or you may want to prep to repair. How is the cab floor? If covered with mat, and if owner will let you pull it up, I would want to see the floor. Floors, rust. Can be repaired but lots of work.
If it starts drives and stops, you can work with the rest.
