I installed the front doors. It was necessary to trim the front lower door skin, as it ran into the front windshield side frame. I installed the cottor pins and an inner upper door seal with teflon tape which attempts to lessen air leakage on the upper door/window. In addition, it was necessary to grind some of the metal off the inner portion of the door handle on the right door, so that it wouldn't run into door skin. Bending it up wouldn't work, as that would cause it to scratch the wing sking when using the overhead latch. I also installed the rear and front seats and fremoved the front window protective cover.
