Notes

• The transition to soft bumpers was completed in 1974 with the introduction of new body color rear bumpers.  The urethane plastic skin had built in recesses for the license plate and the taillights, and a vertical center seam divided the two main sections.  (Later years are one piece without the seam.) The skin covered an aluminum impact bar mounted on two telescopic brackets.
• This was the last model year for the Corvette to exclude catalytic converters.
• It was the last Corvette of the era with true dual exhaust.  Resonators were added to the exhaust system.  Exhaust tailpipes exited below the bumper.
• Fuel requirements were 91-octane leaded or low lead.
• Radiators were redesigned for more efficient cooling at low speeds.
• Shoulder belts on the 1974 coupes were integrated with lap belts for the first time.  Shoulder belts remained optional in convertibles and, if so equipped, were separate from the lap belts as before.  Also the locking mechanism was changed from a pull-rate type to a swinging-weight type activated by the car’s deceleration.
• The alarm activator moved from the rear panel to the driver side fender.
• The stock inside rearview mirror increased in width from 8 to 10 inches.
