[W126 Coupe] Rear End Thumping

[Alexander Hochhausl]

To tell you the truth I really don't remember - probably aftermarket. I
have the receipt, but am too lazy to go dig it out:)

I'm looking for the mount and bearing - might as well do both. How much
will that run me & can I have them before next week end? Do you take
credit card or paypal? It's an '89 SEC 560.

Thanks.

Thank You,

Did you use genuine or aftermarket?  AM rubber bits don't hold up as 
well IME.

As markus mentioned, I can get you what you need..:)
