I Just bought a 2004 convertible mustang 40th edition. it has extremely low miles for the year. my question is the driver side door is tweaked at the top and it will not let the window seal properly. I was wandering do i have to use a door from a convertible or can i use one from the coup. I know there is a difference in the height of the roof line between the two. so I'm not sure if the doors are inter changeable.
