I have a 73 mustang Mach 1 that I am replacing a b&m shifter back to the original automatic shifter that came stock with the vehicle. I’m having a hard time trying to figure out if this car uses a shift cable or shift rod. My transmission has this code stamped on it; e7tp-7006-ca and 68 stamped below it. Can anyone give me advice on what kind of cable or rod I need? Thanks
