rear headrest

Hi there, My car has leather headrests with abs plastic covers. I've noticed one of them has snapped in multiple locations and now hangs loose on the poles. The part does have a code to identify it, but after searching on Google or other threads I haven't found any place to buy spares from...

Does anyone know if the plastic back panel is available or will I have to buy a whole unit? This one if from a car with a black leather interior.
