I have a first generation 50 I stripped the clicker knob set screw. Any Idea's on finding a replacement part?Penn 50.jpgClicker .jpg
While I can't find one that looks like yours, I would try mysticparts.com
It looks to me that you will need to replace the entire assembly. It's not hard to do.
It will knock out. The new one drops in with a retaining nut on the inside,
