The interior door panels differed a bit between models. Small body doors were the same from 1970 to 1988 as were windshields and other components, both body and mechanical. But, yes the 2 door versions were longer. On the SX/4/Spirit Hatchback AMC just repositioned the standard window frame to fit the roof slope.
