Re: Front drivers side engine to crosmember mount
I do not know of a the 164 specifically, but I had the seals in my 75 replaced, cost £100 at a reconditioners, they also reset the shims, re-greased atc. That was a ZF rack, a 164 may be TRW though, I cannot recall but its ballpark.
Where about in the world are you?
as far as availability of the engine mount, try Desira in Diss, Suffolk their parts dept is excellent, 01379 650161 and they do a great postal service. No connection, just my dealer of choice for years and they have never let me down.
