I got into a fender bender, well more like a mild front end destroyer a while ago and it broke the black piece of high-grade plastic behind the headlights. It sort of broke in place, so my headlights stay put but one is slightly off. It the thing you pull the clips up on to reach the headlights. Has anyone else got into an accident like this? and had to find a new part? How hard to replace?

sounds like it's the mount panel that your talking about.
Is this the part your talking about? (click the view illustration link in there too)
