Exterior Visual Clues (most reliable):
* GT badging: The most obvious clue. Look for "GT" badges on the front fenders and the decklid (trunk lid). Beware of fakes – someone could have added these later.
* GT specific trim: GT Mustangs had unique styling cues. Look for:
* Taillights: GTs had unique vertical taillights. This is a strong indicator. Non-GTs had horizontal taillights.
* Front Grille: The GT had a unique grille with a larger, more prominent opening.
* Side Stripes: While optional, GTs frequently featured side stripes, often with a contrasting color. However, these could be added or removed later.
* Fender Scoops (Fake): While not actually functional, many '67 GTs had faux scoops on the front fenders. However, these could be added later.
* Exhaust: GT's often had dual exhaust, but this wasn't exclusive to the GT.
Interior Visual Clues:
* Instrumentation: GTs usually (but not always) had a larger instrument cluster including a tachometer. Check the gauge cluster. The absence of a tachometer doesn't automatically rule out a GT, as it was an option, but its presence is a strong hint.
* Interior badging: Some GTs might have had GT badging on the interior, but again, this could be added later.
Under the Hood:
* Engine: While not definitive, GTs typically (but not always) came with a larger engine, such as the 271 cubic inch (4.4L) V8 or the 390 cubic inch (6.4L) big block V8. The engine code stamped on the engine block will tell you the displacement and type of engine. However, someone could have swapped engines.
* Suspension: GT's sometimes had a slightly upgraded suspension, but this is hard to verify without expertise and detailed inspection.
Documentation:
* Original Build Sheet: If you have the original build sheet (a document showing the car's factory specifications), it will definitively state whether it's a GT.
* Title and Registration: While unlikely to specifically say "GT," the paperwork might offer clues if it has ever been documented as such.
Important Note: Many Mustangs have been modified or restored over the years. The presence or absence of any single feature isn't conclusive. To be certain, you need to look at a combination of these factors and ideally have access to build sheet documentation. A Mustang expert or a Mustang club might be able to help you determine if your car is a genuine '67 GT.
