This is a Super Shifter III mounted with the Supershifter install kit. It did require butchering the floor. If you don't want to cut the floor then mount it on the standard Competition Plus bracket. They never made a kit like this for the E body because the shifter is already high and rearward. When I bought a SuperShifter for a Cuda back in the early 70's I called Hurst and asked why there was no listing for an E body kit and they said just buy the tower and a 7" straight handle, no need for a kit. The kit was for A and B body cars that had the forward mounting point.
