Lather rinse repeat:

The belts should be attached to the roll bar and above your shoulder height. Several pictures of the arrangement in the other topic.

Many questions and trade offs about having passenger side harnesses and their location. As with drier they should be above shoulder height to avoid compression. There is also the concern that the harness without the roll bar keeps the passenger upright in the case of a rollover which makes them the roll bar. Not good. But the chances of a rollover are far less than a collision in which case the belts are useful. You have to decide. But in most cars the cross member behind the seats is not structural. Measure to see if it is the same diameter as the roll bar tubing to be sure.

Good luck.
