Yes, these are registered as '65s (mine included). I've learned during my ownership of my early mustang version (May 64 built) that August 64 is, approximately, when the change-over occurred. In those days, the upcoming new model year debuted in the fall.
I feel many of us use the term "64.5" as a way of describing how the early versions (March through August) are different in a number ways from what was produced and available when the "fall" models debuted. Anyway, this is how I see it.
