I trully don't know? As when I search for the bolts they were saying the eccentric are the same for the w210 and w124, I then thought it'll be the same set up and that the regular bolts were factory fitted first?
Better let the OP look at his bolts like you did. You pictures are great too, you can see clearly, this is usefull.
Its a wee odd that they fitted those right away as its more adjustement they have to do when building the car? no?
I am happy to have the regular tho, no adjustement needed here.
