Hello 65,
If I was you I would call Potomac German Motors in Maryland, (largest MB recycling operation in US). I am sure they have a couple dozen or more wrecked MLs. If you live within driving distance, pick the part up yourself and save. They use to have $99.00 days during which you pay $99.00 for anything you could carry out!! I don't know if they do this anymore.
It is an amazing operation. I am sure they have a web site, or you can phone and they ship worldwide. I don't know how there prices are on this kind of item. I have a friend who makes pilgrimages there several times a year. He always brings back a truck full of unusual goddies for modern Mercedes cars.
