When you replace the speedometer, go to your ACE or True Value hardware store and buy 4 small wing nuts to replace the regular nuts. You may need to file the ends of them if they're too large, but you won't have to remove more than about 1/16" on each ear. If you ever have to remove the speedometer again, you'll spend a lot less time and you won't need to stand on your head.
If your going to remove the speedometer, it helps to remove the radio grille, that is if, you don’t have a factory radio.
An alternative to the wing nuts was to use brass knurled nuts to replace the mounting nuts on the gauges. this, I learned from another “Bolter” on this forum. My apologies to that “Bolter” for not remembering his name.
