Help - Can someone identify this piece?
 

Hi everyone,

I was lubricating my 987 convertible moving parts, track, arms etc when I heard something drop, I look down near the drain and find a black cap looking part. It's the circumference of a nickel, dimple on one end and hollow on other. Please see pic. For the life of me, I couldn't determine where it came out of?? Can anyone identify? Thanks in advance!http://986forum.com/forums/uploads02...1720184650.jpg
