* Exterior Visual Cues: This is the easiest way, but sometimes parts have been changed over the years. Look for these features:
* GT badging: The most obvious clue. Look for "GT" emblems on the front fenders and possibly the rear decklid. Beware of added-on badges; these can be fakes.
* Sporty Stripes: GTs typically had side stripes, though these were optional and could be removed or replaced. The stripes had a specific pattern and color. Original stripes are a good indicator.
* Taillights: The GT had unique taillights. While the basic shape was similar, the GT lights had a different internal lens configuration.
* Front Grill: The GT grill often features a different texture or pattern compared to standard models, though it's subtle and sometimes hard to distinguish without a direct comparison.
* Exhaust: GTs often, but not always, had dual exhausts. Single exhausts were available.
* Wheels: GTs often (but again, not always) had specific wheel styles, though these could be changed.
* Interior Visual Cues:
* GT badging: Again, look for GT badging on the interior, such as on the instrument panel or steering wheel.
* Gauges: GTs often, but not always, came with a special instrument panel including a larger tachometer.
* Interior trim: Some trim materials and colors were specific to the GT package.
* Documentation:
* Original Build Sheet: The most definitive proof. If the car has its original build sheet, it will clearly state whether it was a GT.
* Original Sales Brochure: These can be used to match the features to the GT options.
* Maintenance Records: Previous maintenance records might mention GT-specific parts.
* Title and Registration: While they might not explicitly say GT, they might provide clues or corroborate other findings.
* VIN Decoder: While the VIN itself won't explicitly say "GT", a VIN decoder can give you the option codes that indicate whether the car was originally equipped with the GT package. This is a reliable but not foolproof method, as parts could have been swapped.
Important Note: Many 1968 Mustangs have been modified over the years. It's possible a non-GT has been modified to look like a GT, or a GT has had its parts replaced. A combination of the visual cues, documentation, and VIN decoding is the best approach to accurately determine if a 1968 Mustang convertible is a genuine GT. Consulting with a Mustang expert or restoration shop can be helpful if you are unsure.
