1968 Shelby Mustang GT500KR Convertible

This 1968 Shelby Mustang GT500KR Convertible is one of just 518 convertibles produced for the model year, making it a rare and highly collectible example of American muscle car history. Finished in its factory Highland Green color with a white power-operated convertible top and black Luxury vinyl interior, this iconic Shelby is powered by a legendary 428ci Cobra Jet V8 paired with a three-speed automatic transmission.

The exterior features a beautiful Highland Green finish with GT500KR side stripes, a functional ram-air fiberglass hood, grille-mounted Lucas driving lights, quarter-panel air scoops, a rear spoiler, sequential taillights, and quad exhaust outlets. The power-operated white convertible top was renewed in 2002, preserving the car's classic open-top appearance.

The Shelby rides on 15-inch aluminum 10-spoke wheels with Shelby Cobra center caps, wrapped in BFGoodrich Radial T/A tires. Its heavy-duty suspension features upgraded front coil springs, an anti-roll bar, and reinforced rear leaf springs. Power steering and power-assisted front disc brakes provide improved handling and stopping performance.

Inside, the cabin features black Luxury vinyl front bucket seats, a matching rear bench, and coordinated door panels. Additional equipment includes a center console, woodgrain interior accents, an AM radio, front shoulder harnesses, and factory-style air conditioning. The climate control system received updated components in 2026, including a replacement compressor, condenser, filter/drier, and expansion valve.

The woodgrain tilt-away steering wheel frames a 140-mph speedometer, an 8,000-rpm tachometer, and auxiliary gauges. Additional Stewart-Warner instrumentation displays oil pressure and battery charge.

The legendary 428ci Cobra Jet V8 features a Holley four-barrel carburetor and a functional ram-air induction system. Factory-rated at 335 horsepower and 440 lb-ft of torque, this powerful big-block engine delivers the performance that made the GT500KR famous. The cylinder heads were rebuilt with hardened valve seats, and a coolant recovery system was added.

Power is delivered to the rear wheels through a three-speed automatic transmission and a 3.89:1 Traction-Lok limited-slip differential. The automatic transmission was rebuilt in 1983.

This rare 1968 Shelby GT500KR Convertible combines legendary Cobra Jet performance, authentic Shelby styling, desirable factory equipment, and exceptional collector appeal.
