Sounds like you are doing exactly what you need to do - take inventory and see what's what. Then you need to decide what you want to do with the thing. We range from show trucks that are far better restored than anything GM ever created, to hot rod trucks that have performance greater than the designers could have imagined, to good orginal trucks just keepin on keepin on, to rusted up rattle traps that could hide in any junque yard that no one would ever suspect that they still ran.
With my truck I went for a rebuilt to my own specification. I.e. I fixed and painted what I felt like I needed to fix and paint.
These old trucks are models of simplicity and reliability. I would continue your inventory and check out how the truck drives (steering, engine, tranny, clutch), how well the brakes work, and how good the electrics are. If all that is acceptable, then do some periodic maintenance and enjoy it.
You can partially fix it up, one thing at a time, and you'll always have a truck to drive. Or if you have space in the garage for 2.5 vehicles pull it apart and go for it. I have a 72 c10 in the driveway I am doing right now.
Everyone's got opinions here, but its your truck, you need only decide what road your headin down.
