1965 Barracuda dash trivia

I've got a '66 Barracuda heater delete car! Original Hawaii car. It's the earliest '66 I've run across with a 8/17 build date. Anyone have an earlier one? It's a strange car.....273 Commando, 4 speed, buckets, console, 150 speedo, tach, 8 3/4, disc brake, HD suspension, etc. but not a Formula S.
Thanks, Mark
