Yeah, I mean the windshield pillar. I just went out to my garage and took what is left of mine apart. Does anybody know how the movement works? I know when you twist the handle, the gears make the shaft rotate, but can't you already do that by just rotating the shaft? Also, can you change the direction the light is pointing with the controls on the inside? All I see is one gear on the spotlight end of the assembly and I don't see how anything from inside the cab turns that gear. I turned the actual light by hand and the gear turned, but nothing else was affected. Do you have to rotate it by hand to get it in the right direction, then use the handle after that? Am I missing a gear on the spotlight end? I probably need a good used one because the rivets on mine where the light housing attaches to the assembly are rusted and I can't remove the nut that is holding the light housing on either. I also measured mine and it appears to be made for a 5 inch lens.
