I'm in need of a headlight adjustment screw for my 04. It's the left headlight. The screw has a ball on the end that broke off, thus my headlight went to the lowest position. Being a shadetree wrench, I took a 6mm button head bolt and ground/filed the head into a shape resembling a ball. It works (for now). The local dealer says that you cant get parts, have to buy the whole assembly. So if anyone has one that is damaged and laying on a shelf, I could use the adjustment screw to keep the XF all XF!
