How do you change the headlight bulbs on a 1996 GMC Siera?

You have to open the hood, unscrew the front turn siganls, remove the bulbs, remove the bolts holding on the grill, release the 2 bottom tabs of the grill(through the turn signal holes), make sure marker lights are disconnected and remove the grill. undo 4 bolts on each headlight assembly and remove/change/replace the bulbs. Intallation is reverse.
