Unusual things on my 1966 barracuda

Extremely late. The cut off is usually July 15 and the first day of the new production year is August 1. I would imagine it is a high vin number.

It almost sounds like something they would do at the beginning of the year as a pilot car. (a car with all options) It must have a loaded fender tag. Are you lucky enough to have a build sheet?

I have a partial build sheet. My shop is in the process of being cleaned out as I am putting up another building. I will look at my title though and get the VIN . I should also be able to get to the fender tag as I believe it is on the car because it should be when ready to paint. It shows as a Formula S,disc brakes and is stamped out as I recall, that i believe is the vinyl top inspection.
It could possibly be the last,or one of the last, big window barracudas built. I'm trying to recall if there weren't other things. I believe the washer pump was a 67 model.
