Yeah we got impatient, and cut it with the die-grinder, sqeezed it with vice grips and levered it out with a screwdriver. Left a bit of a mark around the hole, but nothing major, cleaned it up ok.
Popped the new bearing in, and the engine in too, got the car started. Would have finished the job but it got too late, will sort out the exhaust, and rest of plumbing/electrics tonight.
