It had the clips at both ends.

I did pick up a card of "assorted" retainer clips at NAPA yesterday. There were about half a dozen clips. One was almost the right size, but it was "right handed" and I need "left handed". The NAPA clip points back toward the firewall when it's on the rear of the link rod (and would point toward the front if it was on the carb end). There's almost enough rod behind the pin on the back end so I got it put together. But I hope I can find the correct one at some point (or two, to replace the rusty one on the front as well).
