Extra coat, stocking hat, gloves, flashlight, funnel, power steering fluid, multi-meter or test light, lug wrench, cheap tarp or plastic to lay on, windshield wipers or rain-x, grocery store jugs of water for you and/or truck, electrical butt connectors, wire nuts and tape will work in a pinch, fuel filter and hose clamps, shop rags, if you can get your hands on a known working HEI distributor - take the whole thing. Check hoses and radiator cap.
Take it somewhere to get the oil changed and chassis greased, and they will probably check trans, rear diff, tire pressure, etc. Take a look at the radiator and condenser fins to see they're plugged up with road debris.
That fuel filter clamp doesn't look like it's all the way on.
Cool truck, good luck!
Oh yeah, and a huge hammer.
