Well, Kirk Doucette has my old 9007 HID headlight conversion kit in his 97, so that can be done anyway. In fact, the Gen 3 reflector style is much more efficient than the Gen 1 (9004) or Gen 2 (9007) setup is.
I originally bought the kit for about $450, and tried to arrange for a group buy for $425 shipped, say, back in May of '02 or so. Nobody was really interested then.
I picked up the X1010s a couple of months ago, and the price on the Sylvania site was "$549 (crossed out), down to $299" or something like that; they've since dropped the price to $249 a kit.
Both kits came with necessary supporting hardware (kit 1 was bulbs, ballasts & ignitors, and plugged into the stock harness; X1010 kit came with complete housings / bulbs, ballasts, wireless on/off keyfob switches, remote relay & all wiring necessary). The 9007 conversion caused you to lose your high-beams, not that you really needed them for 80% of your driving anyway - that was the only thing I didn't like about them at the time, was for really long dark stretches on wet asphalt, it was harder to see with them.
