Well as Im sure you know, our headlights are sealed beam headlights. So when you want to replace the bulb, you have to buy a whole new housing with the bulb already in it. Check this out:

All you have to do is carefully pry out the factory bulb, and then silicone the hid bulb in, but leave the little clear plastic ring that the bulb comes with on and use it like the guy did in the thread.
Its exactly what I did, and Ive had no problems with it for 2 years, and theyre much brighter. As for the HID kit itself, I bought it from here:

They make some great stuff, I have the same kit in my truck too, thats been going good for a year now too. If you want hids for just your low beams, get a kit for 9006 bulbs, your highs are 9005 i think. Id also recomend getting the slim ballasts as our engine bays are tight, but you could squeeze in the regular ballasts. But once you seal the HID bulb in the housing, its just a matter of hooking up the connections and your done.
