This 1959 Chevy Impala Hardto, Sedan, Wagon, Convertible LEFT Fender Molding is an original GM part that has been professionally polished to show condition. The left and right are NOT interchangeable. The "new" top edge (that normally goes against the door) has a slope. If it slopes LEFT to RIGHT it is for the driver's side. If it slopes RIGHT to LEFT it is for the passenger's side.
