The belt question is a problem here in Australia, from my inquiries the only real difference between Americian seat belts and Australian belts is the Australian belts are soaked 'in a bucket of water' and then retested. Its a shame as the Americian belts are definetly better than the 'Kangol' magnetic belts that were legal and fitted to our 70's Valiants.
My 70 VG Pacer which I bought new kept coming undone to the point I adapted retractable and chucked the magnetic ones. So much for Australian standards and their testing.
My '70 Challenger has the original retractable belts and I won't be chucking them.
I'll do what it takes to register...........
