6a.) There's a round rubber grommet, about 3/8" in diameter, a few inches above the door's latch mechanism and out toward the edge of the door on the driver's side. If you remove this and look inside, you'll see a long grey pin, about 1/8" in diameter, running horizontally from the outside to the inside of the door. I can't see what it does when I pull the handle, but there's a white plastic piece behind it that shifts in position a bit as the door handle is pulled open.

6b.) The rubber grommet, and the long grey pin visible through the hole, are both absent on the passenger's door. I can see where the pin would be, but it's just plain missing.

Unfortunately, my Chilton's is over at another house right now, so I can't get any farther tonight.
