i have a 2001 silverado. i've been noticing more that the new style 04 grille has a sportier but classier apperance than mine. but i don't want to go buy a newer truck either, i've only had this one for around a month or so. so i was wondering if i could get a newr style grille/headlight/hood ect.. and swap it to my 2001? if so, is it a direct bolt on or do i need to have body work done or welding?
