1966 Valiant window cranks

Well, the knob fell off on my driver side window crank. Now, i have fixed other knobs before with some serious glue. but now they don't move.

1. Does anyone have a good fix for these things so that they still spin?

2. After a quick search online, i've found some aftermarket ones, but they are listed for 1967-72 or so. No '66 and before. So i thought i'd get some people's opinions on how these later ones fit early models. Or do they fit at all?

Anyway, just throwing it out to this forum, since it deals with early A bodies.

edit: the crank still spins, but i want the knob at the end to spin, if that wasn't clear.
