Below is listing of 1973 Corvette production numbers and RPO codes.

Model Year Highlights:

  • Safety improvements for the 1973 model year included, redesigned front bumpers to meet 5-mph federal crash standards, and interior beams were added to the doors for increased side-impact protection.
  • A new coolant recover system that consisted of a holding tank which received high temperature overflow coolant for cooling where it would then return to the radiator.
  • Increased sound insulation was added to the 1973 model and the lifting windshield door panel at the base of the windshield was eliminated. A new cold air induction hood was introduced.
  • 1973 marks the first year that radial tires were used on a Corvette.
  • According to the "Corvette Black Book" by Mike Antonick, "4,000 serial numbers were never built. The last 1973 Corvette's serial number ends with 34,464, but production totaled 30,464. The unused VIN numbers were 24,001 through 28,000."
