In January 1961 GM began date coding spark plug wires for their own internal identification. 1961 Corvettes built prior to January 1961 did not receive date coded spark plug wires. Research has shown that most Corvettes had spark plug wires that were dated from 1 to 4 quarters prior to the build date of the car. That translates to a time period of 1 to 12 months. Production runs of a particular model actually began in September or October of the previous year. Example: The first 1964 Corvettes actually left the assembly line in September or October of 1963. Keeping this in mind, you should determine when
your car was manufactured and order the date code (year and quarter) for your spark plug wires accordingly.

Below you will find our recommended Corvette Spark Plug Wire Dating chart. The VIN numbers shown are the last 5 digits of the Corvette's VIN number. This number corresponds to the Corvette's build sequence number.
