Hi Leo,
the part number for the support is:443 511 329 B
But you can get the rubber mounts alone. They are mutch cheaper than the whole support an very easy to fit in.
I think you want to change the support because of ugly "klock" noise at surface unevenesses. I changed the mounts on my car and it was very simple to do.
The part number for the rubber mounts is: 443 511 247 D
you need 2 parts per side (4 parts for both sides)

Beste Grüße
Tim
