Hydraulic strut for boot floor board (W211) I need a replacement hydraulic strut for the rear-most boot floor board in my 2009 W211 estate, the part number is A2119801064. I have cracked the red plastic ball socket at the top so need to replace the whole unit unless anyone knows of a replacement ball part I can fit. The manufacturer is Stabilus and it is one of their Lift-O-Mat units. If anyone has one, would appreciate cost for unit plus shipping. Thank you in advance.
