Thanks for your response. Can you point me to where I might find these "right tools". I'm not opposed to buying the right tools. I simply cannot seem to find them at 33 mm / 34 mm.

If new headsets would wind up cheaper than than the tools, I'll probably go with the new headsets. I'm all vintaged up at the moment and I don't anticipate any additions unless it's something super special. Now that I've encountered this, I would also measure the headset locknuts on any future acquisitions before committing and factor that in.
