64 Dart Gt 4 speed won’t shift into gear ??

The clutch itself is pretty simple. Just 4 components. The linkage is something else. There are lot's of pieces and everything has to work perfect or you may have issues. Good thing there is a little slop built in to each linkage piece which equals the free play. I ruined the first clutch in my 66 by adjusting the free play and not checking the gap. The throw out bearing was riding on the fingers at all times and the bearing seized. It ground up the PP fingers. And yes, it had the perfect amount of free play at the pedal.
