I have a 1999 Gmc Sierra and was wondering if a 2001 yukon denali front end would just bolt up to my truck.. Would i need to change the hood, or the fenders?? And would i have to change my my grille or could the bumper cover go under my existing grille? Any info. would be great. Thanks

 

i thought the only difference was the lights and grille? Pics?

 

You don't need to change the hood or fenders and the stock headlights can be used. Of course you probably want to change out the headlights for the full effect. You will need the front bumper cover, inner bumper, bumper bracket, driving lights (fog), and grill. The C3/Denali grills vs the regular Sierra's are a different shape where the bumper meets the grill, so they have to be matched with the corresponding bumpers.
