1968 Barracuda Seat Belts Retaining Clips

[Faz]

Hi! What is the right location for front seat belts retaining clips on a 68 Barracuda?
I have 2 points lap belts only (not retractable). Any difference between driver and passenger seat? Is it one retainer each seat or it’s a double retainer on the driver one?
On the seats I’ve received (Dart) there were one each seat (in the pic).

Nobody?
I would like to know:
-Were only the retractable seat belts available or also non-retractable?
-Were the seat belts retaining clips available for 3 point belts, 2 points retractable, 2 points non-retractable?

Mine are like these now, non retractable:
