1986.5 D21 PickUp door lock linkage problem

The driver door lock linkage on my 1986.5 D21 Pickup has disconnected. Although it is reasonably uncomplicated to get into the innards of the door, it is not clear how the linkage connects.

My Chilton and Haynes Manuals help not at all, and the only parts schemata I've found online does not seem to indicate the part I have in hand.

I'm hoping someone here has some experience with this. Please look at

Fortunately, my automatic door opening mechanism works so I can get in and out.

Any and all suggestions are appreciated, particularly any indication of a source for a parts schemata and/or source.

Thanks CR
