Do you have the details of SO? I would like to contact them.
Sorry please, Kurt, I apologize. :'(
I am sorry I confused you. With "SO" I meant "someone" but nobody special.
You might want to contact Dan Caron (Benz Dr.) at least for the chrome parts; but I doubt he has (many) RHD parts for our SLs.
I don't know too many used parts dealers in the US anymore today. One may be Sam Mc Cready in Madison/WI. I bought a bunch of parts ~ 8 years ago and know that he is still alive selling.
Also, check ebay regularily; you can then also contact the sellers offline and ask for a specific part.
I have a few addresses in Germany (mainly only for LHD parts); you may want to contact me via PM if you like.
Good luck & best regards,
Achim
