So I have seen the headlight mod and think I want to give it a whirl. Found raw projectors and I don't think it will be too difficult, except for one thing. When you cut the factory lens out, leaving the 16th of an inch border, have you guys been cutting your own clear plastic for that or buying it prefabbed? In one of the mod threads it sounded like he got it prefabbed. If you cut it yourself how do you shape it for all the curves on the factory one?
