the '65 is 97+ for both N/A and */C. 96 for the */C. They are not electrically compatable. You would need to get the PCM from the donar car if you were to use a 60 in a 65'd car, or a 65 in a 60'd car. They would physically bolt up though.. since the subframe is the same for all SI and SII cars, but not the SIII.
Why are you asking, anyways? Transmission swap? You pretty much HAVE to get the tranny from your year and trim level [well, N/A if you are N/A and */C if you are */C.. SE or SSE doesn't matter really]
