All VW / Audi / Porsche engines spin in the same direction. Most
manufacturers engine spin the same way, the exception to this is Honda.

I never knew the Golf series slush boxes were the same (less the planetary
gears)... too bad the manual boxes were the same or else I would have a
Quattro transmission in my Syncro and could finally delete the VC for
Quattros much better Torsen differential setup.
If you want to send me the photos and a write up about them I will gladly
post them on my Vanagon section of my site.
