Sorry you are dealing with a battle with cancer. I had a bout with Stage II brain cancer (ependymoma, 4th ventricle) almost 10 years ago. By some stroke of good fortune we caught it early, before I had any symptoms. That, a skilled neurosurgeon with a great team, and my wife who kept me alive during my recoveries, all combined to give me a new lease on life. I am now a 9 year, 4 month survivor. I do have some side effects which pretty much forced me to retire medically (I never wanted to retire as I loved what I did for an occupation, owned my company I started 29 years prior). Our pony cars provide me a nice outlet, where I can tinker with these awesome cars, and chime in when trying to share useful diagnostic/repair suggestions. It helps me feel like I am still relevant.
Anyway, I sincerely wish you well with your cancer situation. I admire you keeping engaged with your interest in Mustangs despite the battle you are engaged in. It takes more than just a notion, as I well know.
