New swivel seat base - this can be used on either the driver side or passenger side. These units still allow you to move your seat back and forth but also allow you to swivel it around. These come complete with the pedestal, turntable, hardware, bushings - all you will need. But just as they were done at the factory you do need to tack weld the pedestal in place. Notes - passenger side is most common - we love the ability to spin the seat around and powwow with family and friends in the rear. Driver's side is more limiting because of the steering wheel....but if you mount the swivel base back 1 1/4" on the driver's side, it clears the steering wheel with one minor back/forth movement. You also have to cut the battery access doors down a couple inches on that side too.
