Left to right adjustment is done by turning the rod (with the small hex end on it) that sticks UP between the headlight bezel and the rad support at the outer top corner of each headlight. The up/down adjustment is done by turning the rod that is behind the inner top corner of each headlight (it is similar but much shorter than the other one and actually looks more like the threaded end of a machine screw sticking out ... you have to look under the rubber strip that runs the gap between the bezel and rad support to see it). Both are done without having to remove the bezel. Hope that helps. Cheers!
