Support bearing/dome bearing defective at the rear: no replacement to be found in the ETK

At present I have a C4 Picasso with defective dome bearings on the rear axle. The car chirps almost permanently when moving in the stand or the ride. After dismantling the dome bearings (top part from the interior) I could also find the cause. The vulcanized rubber on the socket worked into the body and the plant surface caused this noise. Small something, I thought and went to the search for spare parts. At KYB I am then after a So-called mounting kit found and was then all the more disappointed when it arrived and only the lower part of the cathedral camp was found. However, seems to be normal and there is only this part with all the relevant manufacturers. According to ETK there is also no further part and now I am at a loss. Does anyone know about it? Is someone familiar with a part number? The so-called mounting kit KYB SM9935 does not contain the desired part and is shot from below with the shock absorber to the bodies. Thank you.
