My chrome guy says I have to take off the upper pivot on the '55 DeSoto hardtop vent wing. How do you get it off? There's a small hole on the bottom of the swivel that appears to have a screw at the bottom that appears to be stripped. Any advice would be greatly appreciated. --Roger van Hoy, '55DeSoto, '42DeSoto, '66Plymouth, '73Duster, '81 Imperial, Washougal, WA |
