Three point seat belt question ‘67 Barracuda

Hey guys,

When I purchased my ‘67 Barracuda it has the original lap belts. I need help determining what these odd pieces are on my car. I have looked in the ‘67 service manual and search FABO with no avail. What it the grey sheet metal clip used for on the passenger side? On the opposing side is a coat hook? Are both factory? Please look at the pictures and let me know.
