Funny story about my 72 c10 (currently working on restoring). Back in 86 I was working at the local Chevy dealer (parts department). My power steering went out, I think a hose broke, and I drove it for a number of days without power steering I assume till payday so I could get a hose. My truck had a nice black SS steering wheel from a Chevelle. Well after strong arming that thing for days it cracked and finally broke completely off while making a turn. Fortunately I had vise grips and I clamped on the nut which cam off so out of desperation I clamped right on the threads and drove for two days with a pair of vise grips. It didn't damage the threads too bad. I finally got a new wheel from somewhere and I seem to remember the nut going back on with no trouble. Those were the days... I think.
