1971 plymouth 340 duster orange crush promotion show car y93

I have a buddy with an orange 71 duster, and his has orange interior. hmmm I wonder if his is an orange crush duster. I don't know his vin number. Did the all orange interior only come in these promotional cars? I was thinking this was available in any ev2 duster that year. I happen to own a fj5 limelight 71' 340 duster. This is supossedly odd, because that color was dropped from the 71' color availabilty, as sassy grass was the new 71' color. I'v never seen another limelight 71. only 70s
