I have a 03 sedan and i've ordered two Front Nissan emblems now and they both don't fit in my grille right. I know there is a difference between coupe and sedan emblem sizes but the Nismo shop assured me it was the right one. Here is a pic if anyone else has had the same problem.

 

You need to replace the entire grill (OEM JDM one is slightly different), you can't just swap the emblem.

 

that sucks, return the emblem and do an emblemless grill

 

dammm this does suck. totally agree emblemless grill
