By the time your car was built all cars had the lap and shoulder belts.
Because of this you will have two belts mounted to each side of driveline tunnel on each side. The lap belt normally installed so it can be held in the console cups while the other belt is shoved between the seat and side of the console or flopped rearward behind the seat when not used.
When delivered believe that the shoulder belt belt at the center was folded up and held together neatly, with a thin light brown rubber band
Hope this helps
Difficult to see the second belt at the floor mount but its there
