The 03-06 trunk emblems have the pins on the back. If the ones you have purchased have pins they are the wrong ones. The JDM 07 emblems for the trunk do NOT have pins and are a different size than the 03-06 emblems. Same goes for the 350GT emblem as well. They are a different size on the 07-08's. I have done the swap on both generations and nothing is the same. The correct parts are availabe from japanparts.com
