So what is an AR? I was a teenager old timers who were very much into A's, Jim Talmadge for one, told me that when Ford upgraded a part for an early 1928 that the new replacement part number had an AR suffix. So people started calling the early cars that had those early parts on them AR's. There was never an AR designation from Ford. Am I correct? Please no I think ideas, only provable facts please.
