Those rear fins and pads come in different lengths and curvatures, depending on whether the car is a 2-door or a 4-door, a Riviera sedan or a regular 4-door sedan, a Special or a Roadmaster, etc., etc., which is why they are not reproduced--too many variations and too little demand. So, make your own or good luck in finding a set that fits or is even available.
