In January 1961, GM began dating their spark plug wires for their own internal identification. Most Corvettes had wires installed that were dated from 1 to 4 quarters prior to the build date of the car. That equates to an actual time period of 1 to 12 months. Corvette production runs typically began in September or October of the previous year. Example: The first 1969 models actually left the assembly line in September or October of 1968.
