1971 plymouth 340 duster orange crush promotion show car y93

Love the orange on orange and just bought an ev2 duster with the orange houndstooth interior. Just out of curiousity, the pictures I looked through of ev2's car (which looks awesome) appears to have 73-74 seats in it. Is that how the car came and it has the black stripes in it also? I'm interested in this kind of stuff and love the orange on orange but was just curious on what appeared to be a later year interior and if it came that way and thats what sets it appart from the 71 style orange bucket seats.
