Hell yeah, those look great. I read on another forum that light output was decreased on a GM Full size truck. I don't possibly see how since you're not painting inside the reflector. But, I'll ask: Is light output affected?
Also, a couple of other forums had people saying the glue that GM is using on the NBS trucks cannot be baked enough to release. Clearly, you were able to though. One site was saying they baked at 150-170, another said 190. I think you said you did yours at 225. How long did the factory one bake before it would release OK?
