I'm  looking for the entire vacuum control system for the locking
differential system on a Syncro vanagon..  There is a control valve(with
knob, nut,  and faceplace) in the dash somewhere, and hard plastic hose
going from 3 fittings on the control valve: two of the hoses to the vacuum
servo on the side of the transmission, and the third hose goes to the vacuum
resevoir and then on to the intake manifold.  There is the vacuum resevoir
which I believe is attached under the car to a frame rail, and there is an
indicator light(with faceplate) somewhere in the front cabin...I'm not sure
if it's on the dash.

I'm a bit hazy about the locations because I'm putting this into my 1983
non-Syncro Westphalia, on which I had the transmission converted to include
the locking differential.  It's installed now and running so if anyone has a
Syncro they're parting out, or a box full of these parts, or knows of a
junkyard with a Syncro, please let me know.

Vacuum control valve, faceplate and knob and nut
Hard plastic vacuum lines
Vacuum resevoir
Indicator light, faceplate(?)
