Anyone know of a nice 2003 grille? I don't want one that bolts over, I'd rather replace the whole grille or cut out the old one.

 

Check through Truckin' or Sport Truck magazine. HUGE selection of GM grilles, as well as tons of trucks in there for new idea's on what you can do. Speed Scene (or Street Scene, cant remember wtf the comp's name is off hand) has some good ones. MIC had a few but ive heard bad things about MIC.

If you want an online store, stylinconcepts.com has a huge selection
