This guy does the best job I have ever seen. I have seen my fair share of retrofits done too. He is so particular on how the whole process is done. Sometimes TOO particular, but hey, you know your lights will not move, nor will they get moisture in them. If you want to do it the right way to begin with, go with Ambiguous. I made the mistake of going with another member on here, (Not Asian Ants ) and WOW. What a waste of gas,money and most of all time. Seriously though, I cant say enough about Ambiguous.
