Rubber dampers in boot

[Kaninen]

I have a Megane 2 cc 2001 model 2 litre petrol automatic
Under the boot there is four red rubber dampers that press on to the glass roof when the roof is stored in the boot.
These are missing and I have problems finding a place to buy them
While driving there is noise coming from the back of the car and I expect this is due to the lack of these.

Can anyone please tell me where I can get these?

Best regards,

Olaf
