My mechanic in Sacramento told me about a bench seat (VW OEM) that
would fit on the rails underneath the screw-down metal covers in the
middle of my Westy.  He was able to track down a used one through his
sources (junk yards?) and we got it for $500.   Now our Westy seats 6
comfortably around town.  We take the middle seat out when we go
camping.
