Bell Crank 911 423 018 01

[RWebb]

I have a bell crank with p/n 911 423 018 01 clearly stamped on it (018, not 017), but I can't find it in the Pelican catalog, at Stoddard's or by a general Google web search (using spaces, ., or - to deparate the groups).

Any body know what year car it is from?

Thx.
