Your bench seat has two electrical connectors for the airbag activation/deactivation sensors. Those who have reported trying to replace the double seat with a single PM seat, which otherwise is easy have not solved the issues of the airbag being disabled and we don't know if all of the airbags may be. I would recommend trying to get a single passenger seat by advertising here for a trade and finding a cooperating dealer/technician to solve the wiring issue.
