Rear track rod
This track rod is the rear one on the front axle, i.e. the one to which the steering shock absorber is attached.
Please look at the photo very carefully. There are many different track rods that have been mounted on G's and they are not interchangeable.
This version was mostly mounted from chassis nr 460 XX 70 07 725 on.
Please measure the length, which you can see on the last 2 pictures.
