If there not so much bushing material to remove would used the old fashioned method.
Take 1/4" dia aluminum rod, make a hacksaw cut slot from the end about 1" long.
Take a strip of some emery cloth about 200# grit, place it through the slot.
Place the rod in an electric drill motor and start rotary sanding until get the correct fit.
That way you know the bushing is "honed concentric"
