no. I've heard it's possible to keep your stock grille and add the '01-current headlights. Probably not.
You will need to swap out the header panel, get a grille, headlights, corners, and other miscelanious little doo dads to complete the swap. just so you know....ALL 01+ headlights and the same. Corner lights as well as interchangable from 01+.
And if you want the grille off an 04-05, you'll need a 04-05 hood. Basically your looking at a complete front end swap. But if your go with a 01-03 grille, you can use your stock hood. '98-03 2wd XLT style(non powerdome) are the same from 98-01.
'01 XLT disguised as a '03 Fx4 Level II
