Sorry to hear about your arthritis. If it weren't for DMSO and infrared light therapy I wouldn't be able to work (woodworker), work on my truck, or play tennis. I have it in my right hand on the top knuckles and it goes down into my index finger, middle finger, and thumb. Good luck with yours! and thanks for softening these guys up on having a Chevy in a Ford - my F1 came with one in it and I couldn't afford to change it. Lucky for me that I now also own a 54 Panel with a 289/C4.
