AFAIK, the 300CE 124.050 uses the standard control from any (W124) w/ a standard suspension application.
I also believe that the only difference between the sportline & standard control arms is the ball joint itself.
The control arm bushings that connect the control arm to the chassis are different on the sportline to allow you to set new toe and camber settings with the eccentric bolt. I believe the ball joints are the same. As stated Control arms are all the same.
