The handle knobs on my recent eB@y acquisition came off. It looks like the peens were corroded to the point where they couldn’t hold.

I’m not opposed to using a non-original part, but the retangular mounting hole is very small. None of the handles on my other reels (Shakespeare, Pflueger, etc.) fit.
Here’s what I’ve got:

Any suggestions?
