I think you would have to look at the dashboard for something that says "Airbag" or "Srs"
One thing that makes your situation confusing is that during the mid 1990s, car companies were transitioning between 1 driver airbag and 1 driver and 1 passenger airbag. The other problem is that sometimes the passenger airbag was an option. It also wouldn't surprise me if some cars had a passenger airbag added sometime in the middle of a production run.
Anyway, good luck. Those cars lasted a long time if properly maintained.
