1966 Barracuda help!!

Thanks guys! The guy I purchased this car from was the original owner and stated he bought it new in 1966 in Canada...Thus, no Plymouth badging front or rear...Not sure if that means anything or not, but it was bought at a Dodge dealer as still has the window sticker...Awesome condition and never outside. I was going to buy just to resell, but gotta keep her!
That makes sense as there is a code ending in 6 that indicates a Canadian built model so that w6 might be it. Usually an export car will have another fender tag that is a big oval shaped thing that says built for export on it. Was the antenna added? There is no radio code so it should have been a radio delete car....at least on the U.S. models.
