Upset with Degree wheel findings

Wow sounds like you have your hands full especially having a house fire on top of everything.
I’m 74 but my medical issues is what keeps me from putting no more than 2-4 hours a week working on the Dart. I have a bad arthritic ankle that the surgeon wants to fuse it together, so I have no left to right motion, which will make me lose my balance. Severe arthritis in my hands. Severe arthritis in my right hip. Recently the day after Christmas, I spent 18 hours in the emergency room because I couldn’t walk anymore due to really severe back and leg pains. This issue has been bothering me for the last three months. At least my mind is still intact.
I have a few little and not so little things that add up. I've had joint pain for decades, and once thought it was "just arthritis" as both my Dad and Gramps had arthritis, but no, it's more like fibromyalgia or similar. A car crash left me with a pin from my left knee to ankle, and my major joints have given me pain for years. I have chronic neck and back pain, and my bowels are terrible irregular. But I refuse to give up, and have many friends who just aren't here anymore.
