I'm gonna guess for front lip choices....or you messed your 9th bumper up (hope not)
Short answer - You can do anything with enough cash and a good body shop.
I would start by taking good measurements and comparing the two -mounting points on fender, headlight location as well as the upper grill. (dont forget what is located under the bumper for good fitment)
I remember people said there was no way to put a FD2/FD2R front on a coupe, but guess what - some one did and it didn't even take too much modding.
