How Can You Tell If a 1968 Shelby GT350 Convertible Is Authentic?

The Shelby Mustang lineage represents a golden chapter in automotive history, where collaboration between Ford and Carroll Shelby produced vehicles of unparalleled excitement. Introduced initially as coupes, the open-top variants brought a new dimension of freedom to high-performance driving. These models combined wind-in-the-hair exhilaration with muscle car potency, captivating enthusiasts worldwide. Central to this appeal is the 1968 Shelby GT350 Convertible, a rare gem that demands careful scrutiny for genuineness. Verifying its authenticity involves examining specific identifiers that separate originals from replicas or modifications.

Production Background and Rarity

Only 518 examples of the 1968 Shelby GT350 Convertible rolled off assembly lines, making it scarcer than its coupe sibling, which numbered over 1,000 units. Production occurred at Ford’s San Jose plant before final Shelby modifications in Michigan, ensuring factory integration. This limited run stemmed from the convertible’s late introduction in the model year, reflecting market demand for drop-top performance. Consequently, survivors today command attention, but fakes abound due to the model’s desirability. Understanding this context aids in spotting deviations from original specifications.

Assembly Line Transitions

In 1968, Shelby American transitioned oversight to Ford, relocating builds from California to mainstream facilities. Convertibles received unique reinforcements for the open body, including a thicker frame and additional bracing. Serial numbers began with “8T03J” for the 302 V8, distinguishing them from standard Mustangs starting with “8T02C” or similar. Moreover, Shelby-specific tags on the driver’s door jamb listed the model as “Shelby” rather than plain Mustang. These details, often overlooked, provide initial clues to authenticity during inspections.

Documentation Essentials

Authentic examples include a Marti Report, detailing build sheets, options, and delivery information from Ford archives. Original window stickers, though rare, specify Shelby modifications like functional hood scoops. Dealer invoices or Shelby American Automobile Club registries further corroborate history. Without these, suspicion arises, as forgers rarely replicate paperwork accurately. Therefore, procuring verified documents remains a cornerstone of authentication, linking the vehicle to its 1968 origins.

Exterior Identification Markers

The 1968 Shelby GT350 Convertible boasts distinctive styling cues absent in base Mustangs, starting with a fiberglass hood incorporating dual ram-air scoops. These functional inlets fed cool air to the engine, secured by chrome twist locks. Side scoops behind the doors expelled heat, while a rear spoiler enhanced stability at speed. Fender-mounted Lucas fog lamps and LeMans-style stripes in gold or black completed the look. In contrast, non-Shelby convertibles lacked these aggressive elements, opting for simpler lines.

Badging and Trim Specifics

Proper badging includes “Shelby” script on the trunk lid and “GT350” on fenders, rendered in precise fonts with correct spacing. Cobra emblems adorn the grille and gas cap, cast in metal rather than plastic. Wheel centers feature spinning Shelby logos, and exhaust tips exit through the rear valance. Any mismatch in materials or placement signals potential restoration errors or counterfeits. Additionally, the convertible top mechanism uses a power-operated frame with glass rear window, standard on authentic units.

Paint and Color Verification

Factory colors for the 1968 Shelby GT350 Convertible included Highland Green, Acapulco Blue, and Raven Black, often paired with contrasting stripes. Paint codes on the data plate must align with known Shelby palettes. Overspray in engine bays should match body color, indicating original application. Modern repaints, while common, may reveal inconsistencies under UV light or with thickness gauges. Thus, cross-referencing with period photos ensures color authenticity, preserving the model’s visual integrity.

Deviations here often expose clones built from donor Mustangs, lacking Shelby’s performance tuning.

Chassis and Undercarriage Inspection

Underside examination uncovers export braces, Monte Carlo bars, and a Detroit Locker differential. Frame rails show factory welds and undercoating patterns consistent with 1968 methods. Suspension includes staggered shocks and heavy-duty springs for the convertible’s weight. Rust patterns, if present, should align with regional histories rather than uniform fabrication. Professional lifts facilitate this check, revealing modifications that compromise originality.

From VIN verification to undercarriage scrutiny, each step uncovers the vehicle’s heritage.
