These are not the cheap harder rubber reproductions that everyone is selling which sometimes leak and don't seal well. These are GENUINE FORD PARTS! Better fit, better seal! Why have to do a job twice because you bought the cheap reproduction? We have tried both in our shop and due to problems with the reproductions we only use the Genuine Ford parts on our customers cars. This does NOT fit the '98 Mustang...only 82-97. Ford part number F4ZZ-9072-DA. This part has now gone obsolete from Ford.
