Any extra seatbelt mounting holes on a 70 Duster

Are these seatbelts then from an aftermarket place and not any 70's A-body?

When I bought my seatbelts I saw Dan201's setup in his 74-75 Dart and that was where the anchor was...but I can't recall where the lapbelt retractor sat??? But it definitely was not interfering with the front seat.
