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

my 1968 Barracuda has a dash tag, so it appears that VIN numbers appeared prior to 1969.

also I have seen comments that some internet VIN and plate decoders are not accurate. Does anyone have names , internet locations on the ones that are right?[/QUOT

15 digit in the corner of the windshield?
