It should be on the part of the shifter you hold to change the gears. The one on my bug, you slide down the stick after removing the shifter knob. Now would be a good time for a pic that I don't have. The quick shift plate does not raise the height of the stick, it just raises the pivot point for the stick. The ball hits the plate and reduces the travel for the shift pattern.

Above is a pic of all the parts in a shift kit, the small half round piece mounts on the shifter and is what aids with the smaller shifter movement as it now hits the plate that you mount on the shifter hole. You have removed this plate already and should still have the other piece still on the shift handle.
Hope this helps......
