I have a 99 gmc sierra 1500 4x4. I want to upgrade to a 2004 chevy silverado grille setup. what all do i need to perform this swap? will i need to swap core supports? or the plastic piece in front of the core support? thanks for any help.

well your going to need hood fenders bumper head lights grille and the plastic in front of the core support if your going to do that you can buy caddy kits for them for 2500 or less on ebay with all the stuff you need if you can get the stuff cheaper or free id do it.

thanks i installed the hood fenders grille headlights signals but i cant get the 04 silverado front bumper/brackets to go on. THe new bumper brackets look similar to the front frame mounts on the truck but there not the same size. Does gm make a different bumper bracket? I had to leave my old gmc bumper on and it kinda looks funky id like to be able to install the new bumper?
