I don't have a JMW arm, but I saw a set screw for the cueing assembly in one of the pictures. This set screw was just to the right of the cueing assembly and just above the cueing lever, screwed horizontally into the supporting member. Perhaps if this screw were loosened, you could raise the entire cueing assembly to the desired height. I hope someone that has a JMW arm can provide a more definitive answer.
