Replacing my speedometer cable

On my 65 Dart im planning on replacing my damaged speedometer cable. Now I know how to remove it from the interior but im having issue of getting it out from my A904 transmission since it looks like it goes directly into the tail housing. Does that mean I have to remove the tail housing to get to it? Im asking that due to a replacement A904 cable that i saw has a plastic clip on one of the ends.
