Serious 64/65 904 trans question

Im new to Mopar, Ive got a 65 barracuda automatic on the floor, Im not sure but it seems that I may have a 64 trans because from what Ive seen the 65 cable set up for a floor shift car attaches to the trans differently than a push buttom set up or even a 65 column set up ...... is anybody out there knowledgable on this subject?
