How many 1972 340 Dusters in TX9 (black) out there?

Correct me if I am wrong but I thought the 2% reflected the entire A-body line (Dodge and Plymouth)for model year '72, not just Duster. Heres mine....I know, sorry, its a 4dr Valiant. Factory original paint...two tone TX9 on the bottom and EW1 on top.
