Yeah, I was just going to say, now is the time to hide the "real" spreadsheet and start another one. The new one should be "flexible" enough to make life happy around the house with your better half. :) Good luck!
That mounting bolt is a little bigger than that spade connector. You might have to solder a connector to the light housing. What usually happens is the whole bolt and nut spin in the plastic housing when trying to remove, soak it good with PB Blaster or your favorite spray.
