blabla on AWD

Hi PerL!

'nother 100 points for you!
Well, go to
http://www.audistory.com/pics/syncro.jpg
to see, what picture fooled me. It is from a lecture at my university
and says "press material of VW" (!)
The words from top right to bottom left would translate as follows:
visco-coupling
driveshaft to the rearaxle
front diff

But looking more closely, I now doubt that this is the front end. 
Can you help me?
Even if it was, it would be a stupid thing to draw the visco directly to
the front diff, if it is 2 metres away! (Of course, one could argue that
it had to be drawn that way, as otherways it would have become too big
or you can say that it is drawn with a little space, so that I should
have realized that it is not directly mounted to the front diff.)
Also look at 
http://www.audistory.com/pics/syncro2.jpg
to see another picture, this time from a VW brochure showing the rear
section of a Golf III syncro. Even I can clearly see the visco! ;)

So, I would really ask my Professor tomorrow, how such a fault can
happen, but he is a Mercedes fanatic and probably does not care...

BTW: Did the T3 really have a Visco coupling?
Do you have a pic of the drivetrain? Really would be interested in the
exact setup. As I always thought it would be like quattro or Porsche.
Was the T3 syncro available with all engines and all bodystyles?
How was the front axle constructed?
(Gee, I know you wish you had never mentioned the T3 ;)
