74 Dart Seatbelts, how do they work correctly?

Taking out the shoulder belt (or leaving it off) is fine if you wanna eat the steering column in a front-ender.

I don't.

A 1967 Dart steering wheel tastes llke blood, I went face first into one at about 40mph, split my lip clean through and knocked out five teeth, wasn't wearing belt at the time, also is a quick way to remove a bench seat, as the seat was completely ripped out of the floor, and when there is a wrinkle in the top the doors don't want to open.
