Eurovans '93-'97 have the seats that can be easily adapted.  I have '93s in my '87 Westy.  From '98 on the rails are different and require more work to adapt.
The late Stow 'N Go seats are great news for Vanagon owners because the supply of EV seats was never large to begin with and the S'NG seats are all newer and, being back seats, are likely to have had much less use than high-mileage EV fronts.

 The seats from a Eurovan (some years, early?) will work and are a
worthwhile upgrade.  After about 20 minutes work on each seat with a right
angle grinder, they will slide into the vanagon tracks.  Better lumbar
support, soft headrest and recline better.
