Additional thoughts would be appreciated!
Mechanic's first rule of stuck parts: Push hard, push a little harder, stop and think.
Left-hand threaded fixed cups unscrew clockwise, looking from the drive side. I don't know what you mean by "toward the back of the frame" - it's better to tell us if you are turning clockwise or counterclockwise, and which side of the frame you are standing on.
For a left-handed thread you should be facing the drive side of the frame and be turning the bolt clockwise to loosen the fixed cup, as Sheldon explains in the section after the description of the tool.
