I've got a set of those too, that I bought from a forum member. He purchased them it Baum tools.

I did try to see if they worked on the rear of a 124 and they did not fit well, so I did not use them, I removed the springs another way. I need to remove springs to get to the heim joint in the wheel carrier.

Can you provide some details?

Does the W124 need some type of spacer to allow the tool to function? I'd like to understand why the tool won't work on a W124???
