Baum Tools Unlimited carries the size you need, although I don't know the specific one you have... also, the threads vary between left-hand and right-hand, for different side spindles, at least on the early buses...
Their number is 1-800-848-6657
Here are ALL the dies that they stock for VW:
Metric numbers: (width of stud being threaded) X (pitch of thread) I think that the pitch is in Threads per Millimeter... you may have to count 10 threads or something and divide that by the number of millimeters that they take up to get an accurate figure for the pitch.
