bb,
I think the issue is that the holes have already been drilled and tapped for Heilcoils which would have made them oversized already so the re-tap is not an option.
Nice tip on the bicycle axles...

Best,
Rob

And don’t tell anyone else, go to your local bicycle shop and buy bicycle axel's with their nuts instead of new bolt and borrow his tap & dies to clean up your threads.
Good luck.
