I think the reaction rod bushes are unnecessarily tight - it's not as if they can move anywhere. I've always been quite "thorough" in cleaning up their housings using a cylindrical sanding wheel, especially round the edge so that the new bush is easier to get started.
I always lubricate with a few drops of oil to help it slide.
I don't bother trying to press the old bush out, nor burn it. I use a small reciprocating saw attachment in an electric drill and just cut a slot through the rubber and then into the shell until it will crumple quite easily.
If you cut at the point next to the rod then it wouldn't matter so much if you overshot a little, as you'd be cutting into solid metal behind the shell, not weakening the housing.
