Mid year 273 in 64 Darts?

Some call the 64 Barracudas 64 1/2 models, I guess because they were introduced fairly late in the 64 model year, but Chrysler never called them that.

Same goes for another pet peeve of mine: calling 67-9 Barracuda coupes "notchbacks." That's what Ford called their Mustang coupes. Chrysler never called their coupes "notchbacks."

But I digress. . . .
