Hmmm...a search should have brought up this thread:
EDIT: Whoa! That was a 2006 posting / request! My bad.
Any tips for what to do if the threaded holes on the brake drum become stripped?
Soak the drum centers overnight w/penetrating oil and break out the hammer in the A.M.
Or if you are handy and have the next larger thread size tap (US or Metric), you could carefully use a "bottoming" tap to create a new set of (larger) threaded holes. If by chance you drill a little too deep into the flange section, in won't hurt anything. You may need to chamfer slightly your jacking bolt ends so that they don't "thread" into any new / minor tapped portion of the flange.
Another option is to drill and tap another set of holes 90 degrees from the existing. It would be easier to open up the existing holes though to a larger size. Either scenario is tough to do, given the relative thin drum material and the axle flange right behind it. It will take machinist expertise and patience.
