After a more and more ratteling car, my turn to have my compensator changed under garantee

. My dealer agreed to this and put the new one in order, telling me that Morgan will not upgrade or give me the possibility to pay the difference for the Centa drive

... But having a talk with the Mecanic which I questioned about the compensator, told me that he just have changed one on a M3W and that the new one would not float in the grease any more but is settled in a rubber.
Is that by miracle the Centa

or just an upgrade from the old compensator?!?
