The passenger side sun visor on my 85 280SL Euro (same as US 380SL) flops down because the ball in the socket that attaches to the windshield trim is loose. Any tips how to fix this problem? If I have to remove the entire visor how do I do this? I did remove the single screw that holds it to the trim but it is still on there very tightly. Does it come off by force or pulling? Thanks for any info......Desert
