David, your linkage is in the same holes as mine is. The difference is that your link is bent and mine is straight between the two arms. Here is the picture of mine.
I hope this helps. Looking at your picture, it almost looks like your link bar may not be original, but I could be wrong there. Mine has tiny holes through the short ends that fit through the holes in the arms to allow wires or pins to retain the link bar on the arms.
