My last (and most difficult) step to restoring my W123 benz has been fixing the sunvisors, more importantly the passenger side. The both hang rather low in your face when extended fully up, and the passenger side has a large tear at the seem which is getting larger. Also the mirror cover falls in your lap when you bring it down. Are these easy to replace, has anyone ever done this? I cant seem to find any sunvisors anywhere, anyone know where i can find some in navy?
