your car is probably like mine (72), the shoulder belt is attached to the ceiling
When you are not using it you are supposed to fold it up and tuck it into a flap on the ceiling
There is a person that makes a 'conversion', there is a strap that hangs down from that ceiling bolt with a loop closer to your shoulder and an inertia real on the floor
I bought one but have not installed it yet
I believe he is in North Carolina
I will send you his contact by PM
