Is it clamped to a thicker steel rod parallel and immediately beneath? It may be the rod which connects the front sway bar to the hydro leveling valve.

why do you have no front levelling valve? the rod is part of your hydro system, has someone junked it?

Good on you Alv,

Respect for putting it back.  A 6.9 without hydro is not a 6.9 worthy of your collection (I also have a G, 2 E63s -212 and 213, and several MB wagens amongst others).
If you have a wreck 6.9 the job will be much easier.  Getting all those bits will be hard but keep me posted.  I over here in West Australia and have a few 6.9s.  I may be able to help if you need pics of RHD 6.9s.

regards from the colony
