You need to have the correct bench seat. There will be slots in the seat bottom frame to receive the two seat back brackets. Mine were hidden when the upholstery shop covered up those slots, so I had to cut slits in the vinyl material to expose them.

In the attached picture you can see the driver's side seat back bracket which is painted black. The slot in the seat bottom is that small bit of unpainted metal protruding through the seat covering.

Hope this helps!
