One of the detent bumps on the inside of my Ez-Loc rudder "casting" is missing. It's listed in the parts list as either the "EZ Loc plunger" or "detent plunger", both names have the same part #20492021. My local dealer does not stock it and says he has never heard of one getting lost. He'll order it for me on Monday.

Has anybody had one of these fall out? Do you carry extras?
