DONT do a retro fit. The light properties of an arc style bulb are different than the properties of a filament bulb, and the reflectors must take this difference into account or you will have glare and frequently no improvement in light intensity. Dont let people tell you their retrofits work properly, its just not possible, and they are usually the IDIOTS blinding me in the middle of the day with their HID's.
If all you want is the color, get some 7" H4 reflectors and some Sylvania Silverstars. Wont cost anymore than 150 or so.
If you want true HID, Sylvania made a Xenarc kit with a 7" round reflector. They no longer list them on Sylvania's site, but they can still be found on ebay , and the cost is better than trying to piece together the wrong stuff anyway.
