During the 1960’s and 1970’s, the automakers used letter codes to designate which car platform the models were built off of. Unlike today, there were basically small, midsize and large cars with perhaps a special model of each available. Following is a chart which you can use to determine which model and platform your car was build off of, and that will help you identify which parts will fit your particular application.
