car is a 1990 190E, driver-side visor clip broke off today! it seems that it broke at where the screw is placed. what is the part number for this piece? and does the dealership or fastlane even carry this piece? never would I think a m-b visor clip would just break off. it's actually a brittle piece of plastic. man, I'm just bummed out about this because now my visor just sags. has anyone replaced one? was it easy? please help!
