Those of you who have enclosed your headlights, how did you do it? I'm referring to closing up the inside section of the opening, closest to the boot lid, that triangular piece that's needed. Also, is it at 90 degrees from the base of the headlight bucket? Does it follow the curve of the boot lid? I'm struggling with figuring out the best way to do this and I'm fairly frustrated. I've been staring at this now for what feels like HOURS.
