I came across the Datsunlovers Door Latch recommendations. They are RIGHT ON THE MARK. I actually took off too much material on NEW latches in the area in RED. Then took off too much material off the top of the latch between the BLUE and RED areas. Carefully studied and welded back the material removed and in fact elongated the area between the two colored areas. Then very carefully formed the area in RED. Now the door latches much like it is supposed to. Just finished up today completely dissassembling the door, welding a cracking mounting area, and insulating the outer skin. Then lubed the front glass guide and reassembled the glass. Also installed NEW rubber/felt strips in the window channel removed from the door. Now the door shuts properly and the window tracks and moves rather easily up and down.
