Seat belt holder

[Jtm35a2]

Where can i find the seat belt holder that connects to the driver/passenger front seats on a 2006 mustang ? I see them listed for the 2010 and up. I want to add a set to my car, tired of reaching behind me to get the seat belt. Thanks in advance

Is there a small strap on the door side of your seat bottom with a snap on it?
