Well first of all the shifter being reverse pattern doesn't do anything for you unless you have a reverse pattern valve body. With that, it gives you P-R-N-1-2-3. As for the Art Carr or Winters shifters, the only difference is the gate, which is interchangeable. You can retrofit a standard shift shifter with a reverse pattern gate if you already have the shifter and want to go to a reverse pattern valve body.
