B Body 904 Transmission int a 65 A Body

I have a 904 transmission that came out of a 68 Charger that I want to put into my 1965 Dart.
Can anyone tell me what I will need different as far as linkage/speedo cable/kickdown etc?
Will I still be able to use the floor shifter I have or will I need to swap it out.

Any and all help is greatly appreciated.
