In old age your memory gets not so good. So when I say off the top of my head that means I haven't looked it up and you can take it from my memory, for what that's worth. And by the way, most VW shops carry for cheap the tool he needs. You can also make one out of a 17mm nut, a piece of steel and a bit of welding. Have one special made for the split case tranny 36's which do not have enough room to get in beside the tranny to remove the filler nut. "Gerald V.

We'll leave it up to Jeff to figure out what other places one might find a 17mm hex wrench.
