What would i need to fit 05-06 headlights on my 04 sedan? A hood and bumper off a 05-06? Or only the hood? Thank you. What would also be the difference, are the 05-06 ones slimmer or wider id assume?

 

It would be a major task and I can't imagine it being a viable thing to do. Here are some pics of the two:

So fender, hood, maybe bumper, grill, mounting brackets? It seems like it was a complete redesign of the front end. Maybe trade your '04 for an '06!
