Story

1968 Shelby GT500KR

The 1968 Shelby GT500KR was the mid-year Cobra Jet Shelby Mustang, marketed around the "King of the Road" name and built as a Shelby special edition of the first-generation Mustang fastback and convertible line. This page treats it as a Shelby American program over a 1968 Mustang base, while noting that later 1968 Shelby production and marketing were closely tied to Ford operations.

The safe, source-backed mechanical identity is the 428-cubic-inch Cobra Jet V8, rated at 335 hp and 440 lb-ft in period-style references. Public reference material reports both fastback and convertible GT500KR bodies, with 933 fastbacks and 318 convertibles. The target record here is scoped to the fastback special-edition parent slug, so convertible-only details are kept out of the identity.

Authenticity review should focus on Shelby-specific serial evidence, GT500KR side-striping and badging, the Cobra Jet ram-air engine-bay equipment, correct power-disc-brake presentation, correct rear drum hardware, roll-bar/interior configuration, and concours details such as KR starter-cable labeling and air-cleaner/decal placement. Exact axle ratios, transmission tag codes, and Shelby serial-number decoding should be verified from a Marti report, SAAC registry record, factory invoice, or build-specific paperwork before publication as vehicle-specific facts.

The gallery uses licensed Commons images and platform video embeds as model-line context. Captions separate representative photos from individual-car originality claims.

Still Researching

  • transmission A reviewed Shelby transmission reference supports GT500KR automatic and four-speed Toploader availability with warranty-tag codes, but exact transmission identification tags and application splits still require build-specific or registry-grade documentation.
  • rear axle Factory brochure now supports GT 500-KR heavy-duty torque-sensitive locking rear axle availability, the 3.50:1 standard ratio for manual and automatic transmissions, and optional 3.00:1, 4.11:1, 4.25:1, and 4.56:1 ratios; build-specific axle selection still requires car-specific paperwork.
  • option packages Package identity is sourced, but exact option-code matrix and mandatory/optional equipment list are incomplete.
  • production Body-style quantities are reported by a reference source; registry-grade totals and drivetrain/color splits were not obtained.
  • paint colors NVSAAC page lists Shelby GT350/GT500/GT500KR paint codes A, M and T; other reference-reported colors were not added without a stronger target-specific color-code table.
