I found the rubber stops you mentioned. See attached picture. The second picture shows the problem I had where the roof was too close to the rear deck. Its really weird that my roof has a dip like that on the underside btw. Anyhow, by adjusting the lower rubber stops on each side I managed to solve the problem. Now there is no longer contact between the roof and the rear deck metal part.
