[Biturbos4] Bose Radio Buttons

[Brent Putzel]

I have been monitoring this list for a long while and I don't remember
this particular question so I figure what the heck.  My Bose radio
buttons for changing the stations (*2001 S4) - particularly button 2 and
3 are essentially loose and can either fall out or simply look out of
place.  Broken is probably the word although I can still change stations
with them although it isn't at all like the other buttons.  
 
Is there a place to get new buttons?  Has anyone else seen this? - a
pretty goofy thing to break (button 3 broke first followed by 2 months
later).  
 
Thanks!
