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.

On the 64 Dart, removing the cable from the transmission involves removing a clip on the outside, and sliding it out gently to disconnect it, then piling it and matching it back up when removing it.

IT may be slightly different on the 65, but I doubt it, should just remove a clip and Ben able to remove it
