Trans cable recommendation needed

So ive gotta ask a question. When using an aftermarket shifter they come with different trans levers. They only ever list the chrysler 727 trans and never say a 904. My Dart has a 904 and i used the chrysler arm that came in the kit. Its a Hurst Pro-Matic. There was nothing for a 904 in the kit. Im assuming thàt the chrysler arm does both trans. Am i right on this?
Thanks Rod
