Thanks for the replies- I have a later model 1992 190e 2.6 with the mono wiper blade. If you look at the picture in my post, those 3 10mm bolts are off. You also have 3 more 10mm bolts to the left of that (not visible in the picture), which I also removed. There's nothing holding that entire assembly to the vehicle now, except for an electrical wire that supplies power. The whole thing is loose, I just can't get clearance.

This picture shows the entire assembly. This is what I'm trying to remove.
