74 Duster bench to bucket ???
If the bucket seats and rails are from a Duster you should be ok. You will need to confirm the drivers seat is centered to the wheel. If they are not from a Duster or a Sport, then there may be issues. The seat rails on the Duster are short. (about 2" tall) The left side of the drivers seat rail on the Swingers & Scamps are about 3" tall. The floor pans are different between the Duster and Swinger bodies. I used Duster Buckets in my 75 Swinger. Attached are photos of what I did to level the drivers seat. When you get your car back set the seat without the carpet and go from there.
