There should be bolts holding the front end in place inside the wheel wells, probably under the front of the truck, and perhaps under the hood (that might just be the grille though). If you take off all the fasteners, it should come right off. You may have to take off some other stuff as well, such as the plastic panels in the wheel wells and the metal guard on the front of the truck.
Unrelated but my general manager just hit her seventh deer the other day with her Blazer. I think she said she has hit 3 with her Mustang, one with her Dodge truck (I've never seen that truck), 2 with her Blazer, and there was another one with a different car. She has a Cavalier that she's been driving but she hasn't had it long, so not sure if the seventh was with that car.
