I only know from what i have come across,in my members rides post I have the pick of the exact same grill with the badges upside down remember?anyways my front badge was alot different.And my rear one was identical to the one pictured.
I was just looking at my GTV front badge and my other GT grill with the center badge mount holes and the holes dont line up with the badge bolts so you could be on to somthing regarding a special GTV grill.
