It is NOT a GT vs non- GT thing.
On 1967 Dodge Darts:
If it was a 273 2 barrel, the car got V8 emblems in virtually the same location as the 273 Four Barrel emblems in the above photos.
If it was a 273 4 barrel, the car got 273 Four Barrel emblems in the same location as the 273 Four Barrel emblems in the above photos.
If it was a 383 GTS produced after February 1967. the car got 383 emblems Under the GT Badge in Front of the doors.
The 383 "Engine Callout" emblem was the ONLY on to be mounted under the GT Badge in Front of the doors.
The V8 and 273 Four Barrel emblems are flat and have studs for mounting. I believe the 383 emblems did also.
