Hi Clemens, John has sorted me out... CX wiper mechanism picture as follows:
[Linked Image]
If you look at the photo, where each wiper axle comes through the body there is an upper and lower stainless clamp which clamps the axle area in place onto the bodywork with the large central axle central nut, under each of the the upper clamp ( blocks) there is a black gasket. In the photo on the right hand side you can see there is a section of rod with nothing attached to the rose joint, this is where the wiper motor attachs. This is the mechanism in a CX.
Note this photo is taken of the mechanism on a right hand drive car, I would think this is reversed for a left hand drive car..

Hope the above helps..
Dave
