The fender tags on '69 A12 Road Runners and Super Bees are coded for 383's as the A12 was a "package" or option that was added to a base 383 RR/SB. Also there were a few, very early first run '69 A12 Road Runners that still had an "H" in the 5th position of the VIN (dash plate) instead of the "M" for special engine (i.e., 440) as on the later production A12's.
