Volvo Repair: Headlight adjuster, volvo dealer, light assembly

Question
Hi, I have a 2000 S40 and the passenger side headlight has a broken alignement adjuster. The plastic ring that holds it into place thru the center of the rear of the headlight is broke. Can this be replaced or do I have to buy an entire new headlamp? I went to one Volvo dealer and he said i had to replace the entire headlight at a tune of $275 and another dealer said I could buy a 3 pc alignment kit.
Help and Thanks.
Tom

Answer
I would go to the dealer that said you can buy the kit and see what they have.I have not seen this kit so I am not positive that is true.the dealer that said you needed a whole light did they look at it and did the other delaer also look at it?what I have seen break is the light assembly its self where you need a whole new headlight.
