Arrange the shift forks(1/2,3/4,5/R) in their neutral position, with the striking lever and rod installed in the rear tail housing, lower the whole assembly onto the tranny with the striking lever moved off to the far right so it can clear the shift forks as you lower it. When there is about 1/2" between the aluminum tail housing face and the center steel adapter plate face move the striking guide (the hub that the shifter ball sits in) to the right so the striking lever can slide in between the shift forks, then lower the tail housing the rest of the way to mate up with the center adapter plate. Practice this a few times before putting any sealant on the faces. It's a tricky maneuver but after putting it on and taking it off several times you'll get the feel of it. Chris
