To continue talking to myself on this thread -- I decided that maybe the little tabs on the retaining disc were bent, just enough to not engage the lip on the pipe adapter. I gently hammered the tabs, and either they WERE bent a little, or the hammering flattened and elongated them enough to engage and hold the spring in place.
I'm not sure how long this will last, but I can at least wait until I have enough other parts needs to get an order together.
