One thing that was not necessarily made clear (no pun intended) is the templates should be referenced from the hinge line, not the hatch openings. Look closely at the pic in the post I linked earlier and you'll see the template edge positioned at the hinge...it's actually shifted a bit, but you can see that lining the edge up with the hinge line would align the position marks with the servo.
