I just bought a new door glass for the driver side door on my 1948 DeSoto 3-window coupe. The glass looks good and I got it from the Ebay glass seller for $45. The pic they show in the ad is not shaped like my door window, but that is just a generic photo, not the glass you will get. The door is hard to open because the rotary lock gets stuck and the outside door handle sags down. Does this mean I need a new door latch assembly? also the window won't roll down and I saw that one of the window wheels or rollers broke off and was at the bottom of the door. I have looked for repair instructions for car doors and can't find anything. does anyone know where I can find the parts as well as the instructions for replacement? Thanks, Marc.
