The "Old Guy" didn't have the correct close ratio three speed, until he gets one he will use one of his circle track four speeds. The photos show the correct way to build the floor to accommodate the four speed. The photos show the necessary bracketry needed to locate the shifter correctly, it must clear the bench seat in all seating positions and also be in a comfortable location from the steering wheel. When using the "Black Widow" on a road course this will be just right.
