Wayne, I sympathize with your pain. When I was having problems with my 911 I figured it would be a good time to replace the two sensors on for the flywheel. There is not much room and getting them back it the right position can be tricky. I had fought with the head temp sensor for a couple of hours trying to get the grommet back.
I had called a buddy that is a professional mechanic. He basically pushed me out of the way, and removed and replaced them in minutes. I paid him for what I figured would be a few hours of me cussing. We were both happy.
If you have ever watched a real mechanic work they can do things a ton faster than us mere mortals.
In the end my 911 problem was the dang coil. The good news is I had the sensors on the shelf ready to go since I planned on replacing them before they went bad.
