Use a hole saw to cut out the rubber, then use a small cutoff wheel on a diegrinder or dremel and cut a slit in the metal ring, collapse the ring and pull it out, the new one is it rubber or poly? If it's 2 pc poly, note that only 1 side of the batwing is chamfered (the side that the old bushing/shell was pressed into), if you want to install the poly w/ no hassles chamfer the other side also, that way it'll go in a lot smoother.

I'd go with TT's method, If you don't have a press (20 ton +). I Did my 82's a couple months ago. From my experience you won't get the metal shells out of the batwing with a hammer. I think you'd more than likely crack in the batwing trying.
I bought myself a little 20 ton press on sale a while ago and used it. I made some tools to do the job. Those bushings were in there tight. I was amazed at the pressure that they took before they came out. And when they did move it was with a bit of a bang. I then used one of the old bushing shells to make a tool to press the new ones in.
I think if you clean up the bores, use a good lube, and put the bushings in the freezer overnight. You out tap them in with a hammer and wooden block.

that's exactly why I went to poly, got fed up w/ all those super tight GM bushigns, I can now replace them very easily if I want to, they tap in w/ a bit of grease to help them slide in.
