Hi guys, I am starting my A-903 3-speed to A833 4-speed switch and when I installed the 3-speed in the car (64 Dart GT) I had to make a floor hump out of sheet metal. Now I have a fiberglass floor hump, but I can't see where to put it. Does it butt up against the re-enforcing plate that has the seat holes in it? Also do I have to move the seat over to clear the hump? Any help would be great.
