There's a lot of good info in this thread, just to chime in and stress that the hole really needs to be re-centered before proceeding. Often the wear is within the oil sink, and that is normally well centered, and you can use that as a visual guide. In your case the wear has gone outside the oil sink; ideally here I use a compass with a wide point and scriber tip and make a now concentric circle around the hole, then file up to that with a round file. Then ream to size for a bushing.
