Thanks for the help. I got to that stage last night but have DEPO full headlamp units to replace and have been struggling to find bottom fasteners to remove original units.
I think part of the problem is I have headlight washers which are preventing me removing the lower trim altogether. I've been told to look for some torx fastenenrs under there but can't see any.
I really want a picture showing me where all fasteners for entire headlamp unit are located.
As I say Google has proved fruitless.
