Free 1976 C10 starts after sitting since 1997.

I got the truck for free from a shred job. When I pulled it out of the hole it was parked in since 1997 to put new tires on it, it drove it self down the driveway. I seriously only touched the steering wheel once. Got the new(used) tires put on it and towed it home 30 miles with no stuck wheels and zero heat in any of the bearings. As you can see in the video, it mostly started right up. I put oil in the cylinders and turned it over by hand, then with the starter after letting the lube sit awhile. Used the starter to blow the oil out, put new plugs in it, taped a plug wire that was chewed by mice, and cue the video. After the video, I backed it out to take it down the street. The clutch wasn't seized and all gears in the transmission worked as well. When I went to turn around, I had to push the brake pedal past some stickage, but the brakes started working as well. Maybe after I get the rack off it, I'll do a walk around video.
