One thing you don't want to forget. See the right door in the attached photo. It has a plastic membrain that is glued in place. This protects the door panel from moisture damage. This part is one of the first things removed and discarded by most technicians who feel the the manufactures have nothing better to do that add useless parts for no reason.

This part is real cheap even from MB. If you need one right away because its holding up your job, I would recommend you at least cut one out of a garbage bag.
