The passenger harness without the roll bar is a personal judgement call, there are a lot of
differing opinions.

They're all structural but to what design. The diameter of the tubing in the rear of all cars I looked at (both Shelby and SPF) was less than the diameter of the roll bar. That was supposed to be the key.
In the case of an accident where the passenger is thrown forward the tube will probably buckle. Do NOT as I've seen some do, bolt through the tube as it will weaken it even more. Wrap the harness around the tube.
For the passenger side you have to weigh the risks. The chances of a front or side event are lots higher than a rollover, and a harness will certainly help in those cases but in the event of a rollover it will almost certainly be fatal. Do be sure the top of the harness connection is above shoulders though.
I had passenger harnesses on my car and discouraged their use.
For the driver side there is a bracket that goes across that allows for robust connection. I had one on my car too.
