If you heat the ring gear up with a torch, even a hand held mapp gas unit, the ring will expand and can be removed from the flywheel. Then flip it over, re heat the ring until is slips on, use a soft brass hammer and seat the gear. Now you have reasponably fresh teeth (assuming it has not bee flipped before) for the starter.
