Duster REAR bench seat material yardage?!?

I just bought a yard of the exact, correct material for my '73 from SMS. You enter your year, make, and model and they present pictures of all the applicable materials so you can pick the one you need. You can find the trim code on the car's fender tag, a 2" x 3" metal plate screwed to the driver's side inner fender and stamped with a bunch of letters and numbers. If you will post the contents of that tag (either an accurate transcription or a clear, sharp photograph) we can tell you a great deal about how, when, and where your car was built.
