The headlight is basically the same with the exception of the bottom, inner side. You need to get new trim pieces called "filler panels" that go below the light, and there will be a gap between the inside corner of the light and the grille, but its not that noticeable. Some might disagree, but in my opinion, its not that bad. I have some of the necessary parts but need a few more to do the conversion.
If you don't plan on getting HID now, and I say this because you can get some places that sell HID to give you a swappable harness that converts our bulb harness under the hood to the new bulbs in the headlights, you'll need to get a new wiring harness. Our lights are 9006, the new ones are H11, before you ask. You can get this from Gary at Innovative Wiring. Just make sure you specify in the notes of the 9006 to "whatever" wiring harness that you need the 9006 male to H11 female sockets. The harness is $25.
You need to do a search (yes, I know it doesn't work that well) for a write-up on this. iFORCE has done one before. Search threads with his name in them.
The swap is better than those aftermarket headlights IMO. Some would disagree, as everyone favors their own opinion. Good luck.
