Nobody offers the service on here that I know of that will do it for the 04-08s, but on hidplanet.com there is a few guys who offer services to retrofit headlights and I know one of them did the 04-08 headlights at some point. The problem is not just doing the headlights there is the setup process after with the black plastic behind the headlight that needs to be cut in most cases.
Retrofitting isn't too hard though, its pretty easy, just do a lot of reading on it and follow along. Its a pretty straight forward process
