I'm trying to do research on if i can install an older 3rd row seat into my
91 syncro.
I'd like to switch over to the old tan seats, and use the 3rd row seat with
the arm rests.
I've heard that the later year vanagons have a narrower seat due to molded
side panels.

I know this makes it difficult for some newer seats to fit into older
vanagons (you need to make the
posts longer).  I'm guessing the opposite is true, but I'd like to double
check.

So my question is, which year 3rd row seats can be transplanted

is it another one of those <>86 issues?
