I could then mount it
on a center in the tailstock and bring up a steady rest and then remove
the tailstock center and using a tiny boring tool, bore the center, but
how do I know the steady rest isn't just a little bit off?

What is the *actual* procedure for this?

Mount in a steady rest, c'drill and bore centering taper for live center.
Then you have a true center to re-set your steady rest (if you need it). It
doesn't matter if your steady rest is not "dead nuts" when you bore your
centering taper, as long as it is close. It will only change the angle
slightly. It will still be on center by the nature of the beast (you have
the O.D. trapped).
