After flipping the two flippers behind the wood panel, there is a screw at the bottom of the handle that goes straight in and a second below the top of the handle angling up. The door handle stays attached to the door panel and has a link rod going from it back to the latch mechanism. Hint, lower the door glass before trying to remove the panel as it makes it easier...less bind at an angle. There are also two screws under the storge compartment door at the rear of the panel.
Good luck, just had mine off last week replacing the door glass that some $hi+ kids broke with a BB gun.($410 list)
