1986 c20 revival

[Jered1987]

Hey everybody, I'm getting a 1986 c20 with 350 4 bolt engine and th400 tranny. My wife's grandfather is giving me the truck when we move down south the body is in excellent condition. The truck has been sitting for atleast 5-10 years but he starts it up every so often and drives it. The axle I'm guessing needs a rebuild because he said the spider gears are bad. I'm probably taking the truck to a shop to have the rear redone. What all does everyone recommend doing on it as I have a two hour trip going through atlanta. I know I'm getting new tires,tune up kit, belts, radiator hoses battery.
