He is a W126 expert and one of the best parts sources for these cars there is, and likes to help out members get difficult parts they need.
I heard he might be able to get you the small amount you need.
I also heard a rumor that George Murphy from Tennessee over at mbca might do a similar deal.
Let the forum know what, if anything you can chase down. Others would enjoy knowing.
