I feel dumber than usual asking this, but how do you hold the inside nut when changing the door lock striker? I started to remove it and realized.......there is no access to the nut which was turning and would have fallen....inside the body? and then I'd be driving to work holding the door closed with one hand. I took the interior vinyl/cardboard panel off, climbed underneath, even tried some of my welding magnets to hold the nut....no luck.
