Genuine Vanagon used Diesel parts are available 
from an English speaking Vanagon enthusiast in 
Germany.

(more diesel Vanagons were sold in Germany than gasoline powered Vanagons)

Good prices, like $69 for a diesel bell housing. 
(all J�rgen's prices are in dollars)
Shipping is a little expensive, but order all 
your stuff at once to save on shipping.  I just 
ordered a bunch of diesel stuff from him, very 
responsive via email....and he even has a US 
phone number if you want to call him.
