Hello everyone, I have a 73 Mustang 351C with a 4 speed top loader, sometimes I can’t get into gear while driving I have to stop the car (unless I’m already stopped) and play with the shifter which i think has too much play until I get into gear and they its fine until it happens again, its not a pleasant experience if ask me LOL I hope is the shifter and not the transmission, assuming is the shifter can I replace/repair the shifter from the inside car or I have to drop the transmission...
