I have a 1967 coupe barracuda with a low serial number and shipped march 1966.

It is well known that the VIN isn't an absolute as with the SO number.
I was simply trying to illustrate that there was no reference to car line in the VIN as the original poster was eluding to.

However you look at the reality of these number they generally are close to the sequence, not months different, probably not even hundred units.

I found this oddity while setting up a spreadsheet for 1968 GTS VINs and Scheduled Production Dates. I was trying to determine the approximate date for a later built convertible that a friend of mine has. Note the two November dates in the September dates. This is owner supplied info, but I suspect is accurate, but you never know. Last three digits are not in the GTS registry.
