The plug will thread out, it's probably just rusted. Use a good penetrating oil (3M penetrant works well) and, as the book shows, put it in a vise, and use a pipe wrench. I just finished the same job, both master and slave, and it was no fun. It took 3 hours to break the end plug loose. The end plug is about 3/4 inch deep fine thread, Just use the penetrant and go easy. You'll get it. Pictures below. Good Luck
