You’ll need the metal piece that attaches to inside windshield that this kind of mirror slides onto to keep in place. You’ll notice some yellow speckles on mirror that must be happening on underside because it doesn’t clean off & it doesn’t have a texture like paint splatter or pockmarks or pitting that I can feel from surface. The swivels both move easily but hold firm. Shows it age for sure but if you want original this will do it.
