If you are also fitting new roof straps remember that the pitch of the two mounting studs at the rear of each roof strap may vary from the original spacing. To compensate for this you may need to elongate the mounting holes in the rear cover assembly to give extra room for adjustment. If there is insufficient tension on the roof straps when the rear cover is closed the side aligners on the straps may slip up over the edges of the roof aperture, especially when the car is being driven. If there is too much tension on the roof straps the rear cover will not latch down properly. Please read and follow the fitting instructions carefully.
