back bench from 73 swinger in 71 scamp?

they fit, have 73-74 dart/duster seat in my 71 dart and they will work, the edges of seats on later ones[73 up] are rounded or cut off looking but will work[for seat-belt retractors] and there is a gap in the carpet area next to door panel area--which i am going to change back to 71 style and eliminate that prob[ i figured this out after i had it recovered--sucks but it happens] seat came with the car so i assumed it was right-----so yea they will work
