yep...header panel, headlamps, cornerlamps, grille & grille surround. I think i've read somewhere that some of the lamp plugs need to be updated, but i don't know for sure.
01-03 2wd XL/XLT hoods is the exact same hood that's on your truck now....and all the 98-03 hoods are all interchangable.
Grilles.....theres really 3 different ones......XL(black/grey bars), 2wd XLT(chrome bars), and the ones everybody likes, the XLT 4x4/ALL EDGE grille(honeycomb). The XL/XLT 2wd are called "closed" shell grilles. The XLT 4x4/EDGE grilles are called "open" shells grilles. So to run a particular grille style, you need to also have that particular shell as well.
