Stephen, there is plenty on this subject on TheSamba. Go to the Forum
section for Vanagons and search for 'Eurovan seats into Vanagon.'
Here's one :

Good luck,

> What I need to know is, do the Westy swivel bases introduce a further complication?  I know the Westy seat cushions are thin and that a replacement seat must not have too thick a seat cushion, but I don't have a regular Vanagon to compare the Westy with to see if the seat rails are substantially different (spacing left-right, profile, configuration, etc).  If you've done this swap or if you can compare your Westy seat rails to your non-Westy seat rails I'd appreciate the input before I make the trip.
