The headlight adjuster screws are located in these 2 pointsImages available only to Customers.
As far as adjusting them yourself, there is so many measurements to take its probrably worth the money to take it somewhere and have it done, by someone with a machine or a chart already set up. I can get you the info on how to do it yourself if you would like. Let me know and I will get it for you asap! Hope this helps!
