Hi Mercedes Fans , I have a 1964 w112 300se coupe with a leaky right front air suspension valve. I need sources for replacing the valve and sources for rebuilding the valve. I have dealt with Star Motors in Endicott , N.Y. and I am pleased with them although they are not cheap. I just want to know if there are any others that rebuild these valves and preferably for less money than Star motors does...? Any help in this area is greatly appreciated !!
