i've got a few jumpseats for sale, these will mount in ANY vanagon, and work
great in Westy's when you need an extra removeable seat behing the front
passenger seat.  allows you to carry 5 safely in your westy.  these include
the rear facing removeable jumpseats with flip up bottoms.  also include all
the hardware, and seatbelts.  they are simple to install, and can be removed
in seconds if you dont need them, or the seatbottom flips up for added space.
these will NOT impede the swival seat mechanism. they work fine with it.   
these are from a '90 carat but fit in ALL vanagons.
will ship.
