1967 formula s notchback

Hi I´m Michael and I live in Germany. I´m planing to buy a 1967 barracuda formula s. The car is a notchback an looks great. fender tag and vin seem to be ok. But I´m confused because I have a book which tells that in 1967 the formula s package only was available for the fastback. Can anybody tell me if the book is wrong or something is not correct with the car. The VIN of the car is BH23E723114509. Se also the fender tag
