Seat Belt Question

Good Day, I am putting back together my 1976 280z 2 + 2 and have a front seat belt question. This car has a backseat and based on the one small diagram in the manual, the shoulder strap from the front seat belt goes through the metal chrome piece that screws into the interior panel under the quarter glass. Now I could be wrong, but then the seat belt goes behind the interior panel and somehow exists in an upper direction and gets mounted by the rear glass near the ceiling. I could be completely wrong, so perhaps someone could help me. I do not know how this exits through the panel. Maybe snap me a photo of where the seat belt exits before it gets bolted up near the rear glass? Thank you!
