on those hi flange hubs you can set up something in your vise to pick up the flange holes. No need to re-lace it.
Be sure to do all of the "best shop practice" stuff on the freewheel first - PB Blaster or Aero Kroil, and maybe even a little heat (heat gun)
and then jig the thing in your vice and have at it.
