Headlight Adjusting Screw

I got a set of HID headlights for my riviera for Christmas, and put them in that day. i waited for night and I went to aim them and make sure they were good, and i noticed one of the screws for aiming it, on the passenger side, is snapped off at the top. I'm guessing the guy who had it before me did it, but does anyone know where/if I can get a replacement? It's on the passenger side light and its the one on the top/side, not the bottom screw.

Sorry guys, just noticed i accidentally put this in the exterior section instead of interior

No, I think you put it in the right section. Interior is in the passenger compartment. Exterior, Engine Bay, or even Audio and Electrical would be fine. I would check in the Auto Parts store. You may find what you need in the "Help" section. If you Google "Headlight Adjusting screws", you'll see several choices. Dorman seems to make several different types. See if you can match it up.

ive been seeing lots of rivs pop up in the yards ..
