I'm about to bring the PC in to have the '66-style dimples removed from the underhood section of the driver's fender. The fender is a factory replacement, unfortunately with these '66-style dimples. While it's in for this work, I want to have a proper factory-looking stamp date put into the fender. With a scheduled build date of 4/20/64, I was thinking of a stamp date that was in line with other original stamp dates, something like 4 2 C2. Would this be a good code to use?
