1972 duster rear seats in a 1970?

Headliner's should be 1970-1972 which is fabric sewed onto metal rods (bows) and hung to the ceiling. Near the end of 1972 to 1976 they used a cardboard headliner. Look at your sail panels. If metal = 1970-72 which is bows/fabric and if the sail panels are plastic they the car had a cardboard headliner.
