In 1969, there were 340 Barracudas produced without the A53 or A56 codes on the tag. As far as I can tell, these were identical to the S other than the tail panel and grill. They even have the 340 S emblem on the front fender. Are you looking for these in your registry as well? I think Govier missed these as well because there don't seem to be any production numbers for them ... I have a 340 fastback ...
