I spoke to the previous owner and he said the previous owner #2 said they were 1974 Valiant buckets. When previous owner #1 got the car, he looked in that back pocket and there was a 1974 Valiant owners manual in it. I have also seen 74 duster buckets with the same pockets. I just hope the pockets don't mess up the installation of the new seat covers! Thanks again, Rog
