Your wiper knob should have a small set screw. The other knobs you described are very difficult to remove - they are molded around the metal from what I remember. Those choke cable and vent cables especially. Restoration companies do manufacture the shifter knob, and of the pressed or molded knobs as I recall this is the easiest to replace. The 55 knobs are pretty much to themselves although the Tbird knobs look very similar.
