A tip, it is near impossible to install the rubber seals on an AD truck with the doors on the cab. I take the doors off, leaving the hinge mounted to the cab. Before you remove any thing, drill an eight inch hple through the inner side of the door, and into the hinge. Then remove the door. When reinstalling it, insert a 1/8" drill bit shank into each hole before tightening the hinges. It works for me.
