A muscle car milestone: The 1968 Shelby GT500KR Convertible stands as one of the most coveted muscle cars of its era, combining Carroll Shelby’s high-performance philosophy with Ford’s raw power and engineering. The “KR” designation, standing for “King of the Road,” was not just a name—it signaled dominance. With only 318 GT500KR convertibles built for 1968, this Shelby no. 04416 finished in Acapulco Blue is an exceptionally rare and highly original piece of American automotive heritage.

Power and performance: Under the fiberglass hood lies a 428 cubic-inch Cobra Jet V8 rated at 335 horsepower, though actual output figures often exceeded that mark. This mighty engine features a functional Ram Air induction system and is paired with a C6 3-speed automatic transmission. A 3.89:1 Traction-Lok rear differential and heavy-duty suspension ensure that power is effectively delivered to the rear wheels. Braking is handled by power front disc brakes, providing balance and control when it’s time to rein in all that muscle.

Exterior presence: The Acapulco Blue paint, accented by White GT500KR side stripes, delivers a commanding street presence. The fiberglass hood with integrated scoops adds aggressive styling and functional airflow. Chrome bumpers, bright trim, and Shelby-specific badging further enhance the unique visual identity of this convertible. A White soft top contrasts sharply with the paintwork, adding a timeless and clean finishing touch.

Interior styling: Inside, the GT500KR Convertible features a black bucket seat layout that reflects both sport and comfort. A wood-rimmed steering wheel and full gauge set provide a direct connection to the car’s performance roots. Like all Shelbys of the era, the cabin mixes functionality with signature design elements, including sequential tail lights and Shelby 10-spoke wheels mounted with Goodyear tires.

Production rarity: Of the 1,452 total GT500KR units produced in 1968, only 318 were convertibles, making this example particularly special. With its matching Shelby serial number 04416 and low indicated mileage of just 10,764 miles, it remains in highly original condition—a rare find in the collector muscle car world.

Legacy and collectibility: The GT500KR stands at the intersection of collectible and legendary. Combining Ford’s potent Cobra Jet engine with Shelby’s performance upgrades and striking convertible form, it continues to hold a revered status among enthusiasts. Its limited production numbers and preserved originality further cement its status as a blue-chip investment in the classic car arena.
