Can someone confirm or tell me how to verify if a bench seat from a 1973 Swinger will interchange correctly with a 1971 Duster? Looking to get my Duster back to more appropriate Factory Built specs and the buckets in her now did not come with the vehicle originally. I have located a Bench Seat from a 1973 Dart Swinger but not sure if it will interchange with my 71 Duster seat mounting position. Can anyone help or suggest how I can verify fit? Thanks Folks...
