The window is visible in the above pic. You can see the red/orange pressure plate. Rotate the engine so that the mounting "foot" of the pressure plate is not visible through the window. Now you will be able to see the clutch disc. Have someone press the clutch pedal to the floor and hold it there. There should be a small gap between the clutch disc and pressure plate and flywheel. With the trans in neutral, you should be able to move/rotate the clutch disc using a long, thin screwdriver.
