New OE Mercedes Rear Lock Vacuum Actuator Diaphragm for the Front Right (USA Passenger's) Door and both Rear Doors. This is not a hatch or trunk vacuum actuator.
There are three of these in each car, and you will need to purchase a separate one for each of the 3 doors.
There are two styles, and this is the earlier style that was stock in W116 and W123 until 1980.
W116 & W123 Sedans require a different metal rod than the W123 Wagons which are not interchangeable, although the diaphragm is the same on all W123 Chassis.
Metal rod not included with sale.
NOS item--no longer available new from Mercedes-Benz.
Fits W116 & W123 Chassis
Please verify fitment in the Vehicle Interchange tab before purchasing.
