1969 Plymouth GTX 440
The 1969 Plymouth GTX 440 is the upscale B-body performance Plymouth built above the Road Runner, tracked here as the standard Super Commando 440 GTX rather than a Hemi or later Six Barrel car. Plymouth's 1969 dealer data book identifies GTX as a hardtop or convertible V-8 model and lists the standard GTX engine as the Super Commando 440-cu.-in. V-8 rated at 375 horsepower and 480 lb-ft of torque.
The same dealer data book makes the drivetrain boundary clear: the 3-speed heavy-duty TorqueFlite automatic was standard on GTX, while the four-speed manual path was tied to Track Pak equipment for 440 and Hemi applications. The performance axle package records support a 3.55 Sure-Grip 8 3/4-inch path with TorqueFlite, while Track Pak and Super Performance axle records support Dana Sure-Grip performance-axle paths. Those package records are listed as model-line evidence; exact ratios on an individual car still need VIN, fender tag, broadcast sheet, and drivetrain inspection.
GTX equipment is recorded from the same source trail: special GTX interior and exterior trim, lower-body black paint with reflective tape sport stripes, heavy-duty 11-inch manual-adjusting brakes, Hemi suspension standard with the 440, F70 x 14 red-streak tires, 150-mph speedometer, 70-amp-hour battery, and bright exhaust tips. Paint and color references are model-line records, not proof of any photographed car's original finish. Production counts are carried as reported reference totals: 14,902 hardtops from a mid-size Plymouth fact sheet and 701 convertibles from corroborating references.
Authenticity guidance stays conservative. A real 1969 GTX 440 should be checked through the body/VIN identity, GTX trim evidence, 440 Super Commando engine and transmission records, axle package evidence, paint and stripe tags, and any surviving broadcast sheet. Photos, badges, auction text, and show captions are useful context, but they are not treated as proof of factory originality.
