I finally used the one I attach the picture off. I used ones` ordered from MB, not SLS. Just had to open it a bit more than it is on the panel holding side. But it is acrime against originality and correctness.
I had the brather tank with the attachable hoses, wich has the rods (top and bottom) thicker than the last type of tank. The clips from MB were for the thinner rods.
I have the side panels also from MB, I bought them 3 years ago. The clips from SLS did not fit the cut openings in the side panels (I do not remember exactly what was not fitting). Therefore I ended up with the electric harness clips.
