I joined this forum for occasional help when working on a 1978 Chevy K20 Scottsdale my son just bought. It's pretty rough, but I'm teaching him how to work on it and he's becoming a pretty good little mechanic at 17 years old. It's got the small block 400 and auto trans, but had the NP203 converted to a part time system with locking hubs. I had to research that because the previous owner had no idea, and I was confused by the labels on the transfer case shifter that indicated a full time system but it had manual hubs. 
I've already gotten great help for a question, so thank you.
So far we've just done the basics, like changing the oil and coolant, plugs, cap, rotor and looking for any vacuum leaks to fix. It runs decent, but his front wheel bearings on the driver's side just failed so I got that back together. I've never seen bearings that dry, it looks like the old bearings were encased in clay. Ugh.
He had a buddy help him with the driver's side floor pan, and will be putting carpet in it soon.
Next up is the cooling system (water pump, thermostat, fan clutch and radiator cap), and while we're at it we'll check the compression and timing chain stretch.
Here's the truck and the repair (new hub, calipers, rotors, pads, wheel bearings and manual locking hubs), once we get it solid then he'll eventually get it painted and make it a clean driver. He absolutely loves it, and we're selling his 1990 Dodge D150 so that he could get his dream truck, a squarebody.
