Paper explination?

i belive that from 1973 - 1976 there was no black belts just dark navy blue, I have never seen a black set of seat belts in a 73-76 swinger or sport also remember that 73 was the last year you got the two piece seat belt, 1974 started the one piece lap/shoulder belt with the need to fasten your seat belts to start the car

Ya owning a 74 Ive heard some interesting things about the seat belt safety lock. about your car not starting, Ive heard that if you dont have the seatbelt wires and seat wires hooked up your engine wont start, but mine haven't been hooked up and my motor starts up just fine.
