It looks to be 1 + 1/8th inches in diameter, and 3/4" wide. I can see no part number on it. And I have not had any suspension work done on the car. The only thing I notice is the car likes to sway on the highway sometimes. So from reading other posts this seems to be caused by the swaybar bushings. But I am not very experienced with the underside of the car, does anyone have a picture of a 190 swaybar and bushing location?

Thanks for the photo of the 123 dave, I will try to find similarities in my 190e.
