this first link you place the order then you tell them what you want.
you need the BI xenon kits (meaning they have high/low) for the xjs and tjs
for the chevy trucks like yours the bulbs are 9006 i believe. the dmax has HID highs, lows and fogs.
you can get a breakdown of exactly what type of bulbs you need on wherever here

basically any ebay vendor sells them at a good price. most are from Beijing
