The shop manual details how to remove a wing. The
first step is to remove the 5 screws which hold the
wing to the frame. (One screw is indicated with a
red circle.)
Next, I removed the division channel stud nut. The
nut and lock washer are on the outside, all other
hardware is inside the door.
I removed the pivot attaching bolt (shown in red)
and loosened the regulator attaching bolts (shown
in yellow).
