Today, when I was at the Volkswagen dealer the parts manager and I opened
up as many different CV joint boxes as we could find.  For those who need a
little background on my quest, I was once told that Audi 5000 Quattro 108mm
CV joints can be made to fit on a Vanagon...

Here are the specs of a Vanagon CV joint: 100mm outside diameter and a 25mm
axle shaft hole.

The theory was to install an Audi 108mm transmission flange on the Syncro
transmission then install a 108mm CV joint and attach the Vanagon axle.
The Audi flange will fit on the Syncro transmission or the 2WD transmission
for that matter.  The 108mm CV will the Audi flange.  The problem is the
Vanagon axle is too small for the Audi CV joint.  The Audi axle is 30mm and
the splines are a little more course than the Vangon ones.  Every 108mm CV
joint they had, had a 30mm center... so, at this point I would have to say
that there is more too it than swapping the flange and CV joint... even the
larger CV joings (the 4Motion is 130mm!) has the larger axle shaft.

So, now I throw a question to the list... the European Syncro 16 CV joints
are 108mm - do these CV joints have a 25 or 30mm axle shaft?  If it is a
30mm axle shaft, does anyone have the part number?
