Greetings from SeatbeltPlanet.com!
We are a full line seat belt manufacturer and have developed a specific line of aftermarket seat belt options for older Porsche vehicles. We can also put new seat belt webbing (in any of over 50 colors) on your original seat belt hardware for any year, make or model!
