I live in the Philadelphia area and have noticed a 2-place bench seat
(blue velour) out of an'85 Vanagon GL in good shape at a local salvage yard. You
can either contact me at the e-mail address below for some info or contact the
salvage yard directly (Connors used truck parts (610 828-2682 ask for Doc). I
have just purchased a similar seat for my Westy. One thing to note is that with
the seat installed (and removing one folding armrest) the sliding door will just
be able to close. Also, the rear bench seat is not easily accessible unless the
sliding door is opened (unless you have an 8" waistline).
        Good luck.
