As I've already told Stephen, I'm posting the following for those that
are curious about the difference between passenger van seats and Westy
seats.

Westy front seats don't extend as far to the front so that they can be
swiveled to face each other and still have leg room.  They're a tad
shorter in height to compensate for the addition of the swivel
mechanism.  The seats themselves are a direct swap, though.
