Saab classic 900 flip forward seat release knob. 

Up for sale is one good used unit.  This INCLUDES the clip (9686841) that attached the release knob to the seat.  If you buy one new, they do not come with this clip!  It makes it impossible to use.  Interestingly enough, the clip itself is now NLA - meaning you can't even buy it new, at any price!  This good used unit has the clip, and will mount properly.  Shoot a little lube into the release mechanisms to free it if it's stuck before you install this clip.
