I believe its the part that causes the turn signal level to go back to "neutral" after completing a turn.

The one on my 1987 420SEL has a broken tab, the turn signal switch's tab which extends and is actioned by this ring works fine when I push on it with a screwdriver and actuate the mechanism in this manner.

Does anyone out there have a W126 parts car from which this piece could be obtained?

thanks in advance
