Had mine apart a few months ago.
1 Remove the 3 screws on insode of tailgate.
2 Remove pull latch from outside side. You will need to allow it to rotate approx 30 deg. and remove the pull bars from each side of the latch.
3 If the tailgate is in the upright position, you need to squeeze the pull bars together in order to lower the tailgate.
4 Each side of the tailgate has a latch that slides into the side of the bed. Removal of these latches allowes you to pull the pull bars through the tailgate.
