How do you remove 2007 Hummer H3 headlight assembly?

I want to put aftermarket headlights in my 07 Hummer H3. I want to know how to remove the headlight assembly. Im not talking about the bulb, i mean the whole assembly. Anybody have any DIY pics or repair manual pics/websites? Step by step directions will be great too.|||Have fun. 6 to 10 bolts on the grille, 3 bolts on the hood latch. Remove the battery, and unbolt the headlight assembly. It's easier to just put aftermarket bulbs in. On passenger side you have to remove the air intake box as well.
