Odd double buckle belts

[Texas97]

In my Charger, someone put double female ended belts bolted to the transmission tunnel side. its odd and very confusing. would it be for a should belt also? i dont have a shoulder belt on the roof. These are annoying as hell and id like to replace with the correct buckle belts in the front, 1970 Charger for reference.

Weird my roadrunner bench and my old 70 Charger had double belts

Those are the correct belts for a 1979 Charger. The second is for the shoulder belts which are missing from your car.

Yes, all 5 of my 1970 Mopars have double belts.
