Product arrived promptly and contains both the wiper arm and blade. I just wanted the wiper arm.
The only problem was figuring out how to fit the arm. The old one had broken, but the aluminium bush that attached it to the motor spindle was truly stuck. I read on a forum this could be carefully cut away with a junior hacksaw, making sure the underlying grooved spindle wasn't cut as well.
This tip worked for me. The rotor spindle has a grooved hard metal attachment that cuts into the soft metal bush inside the wiper arm. Once the old bush is cut off all that needs to be done is push the new one on so the blade is at the correct angle on the window. I lightly bolted it on, switch on the ignition to test it was in the right place and then tightened the bolt. Job done!
