OOPS, someone made a mistake

it's been like that since the 80s.i wonder if it's meant to be for the 8.75 7 anna quarter.i pulled a 65 rear apart a while back and it had a tiny carrier,ring n pinoin and spider gears.the rear came out of a slant 6 coronet.
Could be south of the border it has a different designation, likewise, Mopar had different designations over seas
