Motor mounts: how to replace biscuits

I got my new motor mount biscuits (for a Slant on a 1974 Dart). Is there any special trick to removing the old and installing the new? My thought is to beat out the old ones with a big screwdriver and a hammer, then press the new ones in with a large socket or something, and finally bend the sleeve edges down to make sure the biscuit can't slide out (the same way the original ones are done). I see that I have to be careful to install them right way up, as the bushing is off center.
