This sounds like a lot of fun. I'm not sure my 45-year-old car would be up for the whole tour, but a NorCal start would definitely get me out for the first few legs.
Sounds like the bolt is binding. I had a similar problem with a steering rack bolt last week. I was able to get a thin chisel under the bolt head and lever it out.
The hinges have to be tight. The nylon sleeve TWard mentions would have to help. My wind wings were from a Triumph, and the hinges are very tight. It takes quite an effort to change the angle. They haven't moved in 4 years.
At first I went over my frame every couple of days with a 3M finishing pad. After six months, though, I couldn't keep up with the rust and started spraying it with WD-40. I washed it with soap and water before painting it.
This is my car and the dead pedal works great. You just need that small tab under the arch of your foot and you can put your full weight on it. I've adjusted it forward a little so that I can just feel the clutch pedal under the ball of my foot during normal driving. Moving from the dead pedal to the clutch is effortless and there is no danger of getting a foot stuck under anything. 200-mile cruises are very comfortable, and the pedal even works for bracing myself in turns.
Maybe so, but I WON!!! So I saved him $44. And in just a couple of weeks I'll be blasting along in my 7 with my cool leather helmet and s***p will be just a distant memory.
