Well, this is some interesting stuff. It looks problematic for Syncros. 
Here are some of my quick observations:

>4 disc brakes recommended DM 3,600.00

A disk brake kit! That is about $2400 (plus shipping, duty, etc).
I wonder what it really is: ideal would be bigger disks up front, and 
a drum to disk conversion for the rear! 

>I bought the assembling kit from Winkler which costs 2,750 Deutsch
>Marks without shipping.

That is about $1800. Similar to the price for the base MSDS kit.

Some elements in the kit, and comments:

>1 clutch housing (I don*t know, if it is from a Volvo or the VW
>light truck LT 35)

I presume this is a bell housing. Sounds like it it a stock part. 
I wonder if it has any part numbers on it.

>1 complete exhaust system without catalyst (which is not yet
>needed in Germany)

Well, it sure is here!

>What you will need additionally is the 240 mm flywheel itself
>and its pressure plate, both parts of an AUDI Quattro. That will
>cost about 600 Deutsch Marks.

I would try to buy the engine out of a quattro, and these parts would
all probably be thrown into the deal.

>The shipped exhaust system will find its place
>underneath the left midsection. Because my vanagon is a camper
>and on that place you will find a 50 liter water reservoir....

I'd like to know if the vehicle being converted is a
Westfalia camper. Sounds like the place where the propane tank 
is located on US Westies. So they have the exhaust system
running forward?

More exhaust  stuff:

>midsection ...

DOH! Syncro owners, this sounds like the place where your driveshaft and
protective bash rails are. 

>...and the pipe will end on the Vanagons south east corner.

With respects to St. Muir, I would presume Front is North, and he has
the outlet where is is now, at the right rear.

Sounds like a complex problem for Syncros. I don't really want to 
lower my engine toward those rocks in the road, there are implications
for the bash rails, etc.. 

>Without lowering, it will be possible to mount everything without
>welding.

But it sounds like you would have to raise the decklid 7cm -
not good for Westfalias, but Helmut does have a camper. The real 
question is how will this affect the sleeping area. Again, perhaps 
his layout is different than ours.

Very helpful information, but maybe not for all of us. I want to learn 
more about the disk brake kit, though!
