I have installed the front seats from an EV in my '91 GL.  They recline
much more and give better lumbar support.  The ones I used were from an
older hardtop EV, not a camper.  I saw a camper in a junkyard recently and
the mounting rails on it were different.
  The EV rail on the bottom of the seat has an extra edge that has to be
removed for it to fit in the vanagon  track.  With a right-angle grinder
this took me maybe 30 to 45 minutes per seat.  Then some smoothing with a
file will make them slide better.
   There was a thread a few years ago about this, complete with pictures.
 Sorry, I don't remember the authors name.  It should turn up with an
archive search.
  I know nothing about the jump seats.

good luck,
Larry A.
