WOW!! I never knew that hook was there! I have a Series One car with a completely original interior and I have never seen this hook until today after reading this post. I went out to the garage, and sure enough, I have the hooks. Cool. Now my seat belts won't hang out the door!

The two pics below are from my Aussie 1970 240z. They are the original fittings.

Hi Mike

I have sent you a PM. And thanks for the offer, I think I will take you up on it.

Hmmm... I see from the pics they changed the seatbelts on the australian cars when they were imported. That is why these clips are useless holding our seatbelt clasps.
