Old style Roofbars (Bilton Road CV22)

I know this is a real long shot but I'm after the old style roof bars for a old car , the roofbars that clip into the door frames that for cars that don't have fixing points rails etc like all these new fancy cars , I'm hoping someone has one of these styles hidden in a garage or back of shed as the real old styles . Many thanks in advance looking for door fitting for older Volvo estate
