You need to find it! This is what happens when one is not accounted for

 

I completely agree but I do not see where it could be hiding. With the main shaft removed I can easily search in the housing. I've taken a small flashlight and even a strong magnet to try and get in the corners. Unless im missing something there is no place for it to go....they fell out when I took it apart after the first time I reinstalled it. So I know it came with all 15 and that I lost one. I searched for hours and thought I'd gone crazy being that it happened right in front of me and I couldnt find it.

 

Any words of wisdom when replacing the cover plate shifter lever o-rings?

 

Yours is different than mine; yours are easy I would guess, because your external shifter arms just unbolt.

 

It looks straight forward but then again everything I touch turns into a project! Thanks for the backup. ..I'll press them out then. I would hit everywhere but where I was aiming if I used a hammer.
