However, the car came with seat belts from the factory it is a 1967. Lap belts became mandatory equipment in 1966. Shoulder belts in 1968, and i believe headrests in 1969 or 1970 per DOT regs. So yes it has threaded reinforcing plates for belts. Car was a basket case when i got it with lots of missing parts. I think they were gutting the interior to start making a dirt track car out of it. Only thing left inside it was the dash, door panels, steering column, and pedals.
