Nevermind...I found a great picture here
DIY Shift Boot Install (thanks e-licious!). I used channel locks on the shaft (with a towel around the shaft), and a plumbers style monkey wrench (again, with a towel) on the knob. A few hard turns and it was loose. Some minor indentations on the knob from the wrench are apparent. I'd use rubber next time.
