71 Demon Seats?

Back seat should be the same as far as I know from 1970-1976 non fold down rear seat didnt change much if any at all. I am not quite shure about the front seats I belive they are considered A BODY only E body seats are diffrent though I think 70-71 A bodys had the plastic back like B and E cars while after 71 they went to full viynl
