The Ford Swivel Seat Base allows you to rotate your seat 180 degrees to face the rear of the van.*
The Ford Swivel Seat Base does not work with a power drivers seat.
The Driver's side Ford Swivel Seat Base does not work with a 4x4 van due to the location of the 4x4 shift levers. The passenger seat still works fine.
The swivel seats work for E-Series vans model year 1997-2014. You may have to move sensors wires under the seat for install. Professional installation recommend but not required.
*Seat needs to be facing forward while van is in motion.
