You will need a LA904. If original your current transmission is dual cable operated - 1 cable for the actual shifting and the other for park. The dual cable transmissions whether slant or V8) are a one year only piece. So if you want to keep your current shifter (whether floor or column), you'll need that 65 V8 904. You can also go with a 66-up 904 rod operated but will have to make other arrangements for the shifter.
