OK after sifting through many visor posts I have my next question. When driving my 53 Bel Air the visor is fine under 60MPH but over that it starts to flop a bit. The Visor is a 2 piece unit with a spot welded seam. It attaches to the side channels above the doors and a center "C" style post in the center. Have any of you stiffened your visors with more sheet metal, cross beams, etc? I really like the look of the visor but I do 70+ regularly and I would hate to rip it off on the highway. Ideas?
