I am afraid not.
I took W108058, which is SEL 3.5L, not sure which one you have...
Left side rails:
Inner A 108 885 03 40
Outer A 108 885 01 40
Right hand side
Inner A 108 885 04 40
Outer A 108 885 01 40
Taking inner left for example - the system says only W108 and W109
Taking the outer left - same, unfortunately.
W111 have their mounting rails with 111 designation, e.g. A 111 885 00 40 inner. Same for left and right.
