Grill Medalilion Question ??

I show my 84 in Division III Unrestored - URB. I've achieved Gold at 4 National shows so far. What grill medallion am I elible for/working toward (if I achieve 20 points)? I noticed a picture in the latest Mustang Times of someone receiving a "white" grill medallion. What's the difference between the Blue, Red and White grill medallions? Thanks in advance.

white is for conservator class cars......blue for concours cars.....red for driven class cars......you are going for blue.........good luck!!
