I too hate to hear of your back issues. I have similar problems and they suck, big time. I hope yours gets better soon.

Nice that you can pass on your knowledge, especially since you are down.

I have only worked on one original early car, a 1930 Model A that a fellow I knew bought. He knew nothing about mechanics, but fell in love with the car. I was tasked with keeping it running and it was a learning experience for sure. Yeah, it had 4 wheels and a motor, but it wasn't even close to things I was used to working on. Just setting the timing was very different. It was the brakes that got me. They scared the crap out of me every time I drove it. Of course, I was probably driving it faster than I should have. I did talk him into letting me rebuild the brake cross bar and they did work a lot better after that.
