Okay, I will try and take this one slow. I am currently in the middle of installing a 401 into my 71 Javelin. I made the decision to change the tranny to torque-flite 727. I got most everything I need except the speedometer cable. I know that the borg-warner cable will not work on the torque-flite tranny and I will need a torque-flite cable. The question is will a 72 Javelin Cable work on the 71 Javelin. My speedo unit is a clip in with the cable and I am not sure if the newer (72) cable is a "clip in" ? Or is it a threaded like the 70 and older AMCs???? Any ideas??
