560 SL trailing arm shackels

[ironman21]

Hey SL fans, Newbie with a question. I have started to remove the entire rear end of my 560sl for reconditioning (bushings, bearings, breaks, shocks etc.) I have the hubs off and noticed the shackles on the trailing arms are installed at different degrees to their trailing arms. Since the shackles are pressed in, I believe that they are in the original position from the factory. I have scoured the 107 manual for information but can't seem to find any. I do not plan to replace these since the bushings are tight and there is no play + they are $250apice. But I am concerned about the difference between the left and right side. In the picture you can see what I am talking about. I will be removing the arms tonight for prep and painting along with new bushings. Got to remove the shock and spring first yikes!
