Thanks for the response. I was just thinking of doing this because of the hole in the left headlight for Ram air. But if it requires replacing the hole front end design, that may not be a way I want to go. I like the whole halo light design and with the Ram air in the headlight I felt that would be killing two birds with one stone. I really do not want to open my factory lights to install the halo rings, and I've seen reviews that the Anzo lights are kind of dull compared to the factory ones. When you say that there are some unique options, what have you found?
