oops, didn't realize you were referring to the coupes only. In that case, you'd probably only have to change the trunk-lid and tail lights. Rear quarter panels are the same, and the rear bumper looks to be the same also. Also, the front hasn't changed that much (Or, at least not enough to justify a swap) except for the grille, which looks as though you might have to replace the front bumper to make fit. Eh, I like the front of the 03-05 coupe better, as well as the rear.
