1969 Plymouth Barracuda Convertible

A 360 bored out to almost 400 that must be a siameses block?? Funny about the production numbers, the '67 '68 convertibles seem to pop up a lot but doesn't seem to be too many '69 convertibles around....

There was
4,228 convertibles in 1967
2,840 convertibles in 1968
1,442 convertibles in 1969

With only 1/3 of the convertibles made in 1969 as compared to 1967 and only 1/2 of the convertibles made in 1969 as compared to 1968 I would expect to see fewer 1969s.
The number of 1967 and 1968 convertibles combined would be almost 5 to 1 when compared to 1969.
