Are these holes tapped and threaded or just drilled? I'd
assume that they must be threaded or else I don't understand
what this fix does.
^^^^^^^^^^^^^^Yes, these holes are tapped, and most importantly they must be
tapped so that the two sets of threads are in synch, so that when the new
long bolt is screwed in, it will pick up on the second set of threads
perfectly^^^^^^^^^^^^^^

So, both the inner and the outer flange of the hub are threaded?
Isn't there a problem getting good quality bolts with that much
thread, then? As I recall, grade 8 and AN bolts only have about
an inch of thread, then the rest is shouldered. I think I'm still
missing something.
^^^^^^^^^^Indeed it may be tough to get grade 8 bolts that are threaded all
the way, but they do exist as that is what I have in my hubs.^^^^^^^^^^^^^^^^
Who brought this subject up anyway ???
