I have several extra inner and outer grille extensions for the 1964 full size cars. All are group 1.266 and are in excellent shape for being on the shelf for 55 years. Certainly proper for a show car but not Pebble Beach perfect in case your car is invited. Most have boxes but a couple do not. Email for photos of ones you may be interested in. I can put together a full set for the Dynamic 88/ Jetstar 88/ Jetstar 1 if wanted. The others are loose.
