I'm looking to buy HID's on my 2001 WS6. I know some companies are offering the composite housing for them, and I've even seen a company selling them as a complete kit with the HID's. I just can't seem to find someone offering just the housings for my car

. I simply need to know, where to get just the housings, and what size housing I need. If any one has done it and has some tips for me, please let me know. I'm trying to have this done soon, cause I just blew my low beam and I really don't wanna buy a new head light when I'm just going to put HID's in anyway. So please let me know....
