I would drill it to the minimum size necessary to get it round again and insert a bushing to bring it back to near spec. Then I would weld the bushing in so that you restore some strength to the shaft. Another option would be to drill a new hole 180 from the existing hole and fill in the old hole with weld. Good luck!
