I have one from Eurocampers.com, it works very well.  Great for camping, I
have more comments about it on the page:
http://www.eurocampers.com/Swivels.html

Mine is in my 87 Wolfsburg, you have to remove the jump seat to swivel the
front seat, you also have to do some small mods to get it in.  I enlarged
the bolt holes in the Vanagon, didn't actually drill out metal, just excess
paint in the holes.  I also removed the metal door on top of the battery to
get the base to clear.  You could either remove the metal door as I did or
the carpet flap.  I chose to remove the metal door so I can still access the
battery terminals if needed, the carpet flap covers the battery compartment.
To remove the metal flap I drilled out the rivets, it could easily be
riveted back in to return to stock.
