OH BOY! I could keep this thread alive for years!
I had a 79 Toyota pickup back when I was single and living in squallor. I had just enough money to pay for the safety inspection, insurance and licensing. Problem was that the horn didn't work, and the tail light lense was busted open. I pulled the steering wheel and found that the brass brush in the the steering column was worn out. I dug around on the floor and found a spent .22 casing, slid it over the top of the brush, and reinstalleded the steering wheel. The horn worked great. For the light, I found a cereal bag in the trash that a big chunk of red printed on it. I cut a piece of it to fit over the lense, glued it on, and passed the safety inspection. Those fixes stayed that way for many years.
My brother was on a hunting trip with his friends, when the fuel pump on their jeep quit. They were miles away from civilization with very little along the lines of emergency tools, food, and clothing (they were dumb kids). In that part of Montana, you could wait for weeks for another living soul to come by, so they had to get themselves out. The Jeep would run if they kept the rpms down, but they got to a point where they needed to climb a fairly steep hill to get up on a road. Try as they might, they could not get it to stay running up the hill. They finally came up with an ingeneous procedure for getting up and onto the road. They took turns walking next to the Jeep huffing air into the gas tank! This created enough pressure to force the fuel through the lines for them to get the rpms needed to climb the hill and slowly drive home!
That same brother was driving "Pete", the 65 Chevy farm truck one day, when the steering wheel popped off in his hands. He grabbed hold of the stub and wrestled the truck to a quick stop. For some reason, he couldn't get the wheel to work, but as he was miles away in the country and didn't feel like walking home, he rumadged up a pipe wrench. He clamped it down on the steering shaft, and drove home using it a wheel.
I have so many more of these type stories that I could go on for pages! (But I wont)
