Considering Push Button Conversion...help

Yeah, you would need a 65 or older transmission to make it work. Sounds like you've got some unoriginal stuff in there if you've got a 727. You'd need a 63-64 Valiant, Barracuda, or Dart dash, the shifter pod, the right parking cable and shifting cable, and a 65 or older trans. While there was no pushbutton in 65, they still used the cable shifter like they had in the pushbutton cars, so it would work if you had on older style 904 or 727.
