The 88 on v-gons have the plastic air exhaust vents at the rear of the rear
side windows.
The design is set to pull air out of the van at the back. They do work and
help the fresh air and heater air enter the van.
You can retrofit these plastic vents to the back of 87 and earlier vans.
I just did this to my 87 syncro.
You will need the window glass from an 88 on as well because it is shorter
to allow for the vent.
There is a rubber channel that the glass sits in to fit into the plastic
vent, dont loose or forget these.
The outer rubber is the same size as the 87 and earlier but the late
weatherstrip has no slot for the chrome trim and is all black.

If you would like to make a worthwhile project of it, pick up a set of side
sliding windows from the wrecker too and adapt them to the rear D pillar
locations so you can not only have the vents in the back of the van to let
out air but you can open windows there too.

I just did this and it turned out cool. with the stock slider glass you can
get about a 6inch opening, if you have new slider glass made you can get
over 8.

I used polycarbonite for the fixed panel behind the slider to accommodate
the angle and shorter length needed. The height is the same.
