OEM Correct EB Seat Belts

[Jaxgtc]

I ran across some perfect match seat belts for my '75 Sport. They are concours correct mustang belts from Scott Drake. Both Retractable and fixed length are available. I needed a set for my rear seat and found them to be an EXACT match with the OEM fronts in my truck. I was ready to buy some used belts and a kit to restore the buckles, but this option wound up being much cheaper.

Question, does anyone know the factory correct rear seat position of the buckle ends? Centers like the front, outsides? I checked tech diagrams and sales literature but could not find any rear seat examples.

Thanks for the help.
