Posted in For A Bodies Only 69 Vs 70 Benchseat Interchange admin August 11, 2008 Besides skin patterns, what are the differences (if any) between a '69 Dart split benchseat and a '70 Duster split benchseat? Will the '70 bolt into the '69? Are the seat adjusters/tilt mechanisms the same? Are the headrests the same? TIA. Author: admin
