One thing I do in removing the switch unit, which helps a fumble fingers like me, is to wrap a thin piece of electrical tape around the joint before I remove the screws. This allows me to keep it all together and get it to my work bench where I can take it apart at will instead of picking up the pieces of it off off the floor of the truck. Put the tape back on when installing the unit and remove the tape after the screws are in.
