Window Blind fasteners
I have a 1997 Coach House. The window blinds are fastened to the body of the van with a screw and a kind of plastic circle to wind the cord around. The screw has come loose on several of the shades, which means they can't be pulled up or down. They are thus fully extended all the time.
Does anyone know where to get these fasteners and/or how to make the screws stay?
