I already have the aluminium adjuster from my old broken headlights, however I feel they are not as good as they seem. Of course they won't break, in fact after the accident the headlights all hancur the adjusters were fine. However, the hole where the screws were to be screwed in were not threaded, and the screw were supposed to cut the thread as they are screwed in, but in mine, after further examination, didn't have proper threads and I was having problem adjusting the headlights manually (adjusting on the headlight). It was just loose. Perhaps the aluminium was too strong for the screws.
