The other grille is a GT/GTS grille. this grille is a Swinger/low line grille and the headlight bezels are painted as GT/GTS bezels. The bezels should be with the other grille in my opinion.
Appreciate the info. This set up came off my 69 GT. As stated the other is an extra that I have laying around. They are both pretty nice pieces. The headlight bezels are usable...
If anyone is interested they can mix and match or buy them however.
