Fiat Dino Seat Belt installation

[babyfacemax]

I have a 1971 Fiat Dino coupe my dad passed down to me. I love it! I want to put a three point harness seat belt in it. Has anyone done this before or know where they should be attached on the car? I have searched around but haven't found much luck....I have been :bang: trying to find something.

Thanks in advance!
