What is it?

As I'm getting to a point to start re-assembly of the '68 Dart that I disassembled over 22 years ago, I am realizing the magnitude of the task. I labeled most of the parts, bagged them, and generally took lots of photos as I disassembled. But, inevitably, there are parts that I have no clue about, the attached photo being one example (some kind of throttle linkage??). I'll figure out most of them with a fair degree of ingenuity. But it got me to thinking about a thread idea....post a photo of a part that you can't identify or one that you think will stump the rest of us.
