if you live anywhere near VA, let me know. i'll give you the contact info to the guy that did mine. absolute superior work and hes the best guy ive seen. hes done probably a 100 or more retrofits, so he knows his sh*t. if you live close enough, he'll even mount the ballasts, set up custom relay harnesses and aim them.
also, i havent gone to the site in a while, but check out HIDplanet.com. they have a lot of information, although i wouldnt try to buy anything there cuz of their inflated prices.
goodluck w/ your job, hope things work out well.
