One caution: Just fixed the antenna on my old Mercedes (same procedure). Part of the old mast was broken off inside the motor, so the new mast would not retract the whole way in. Left about 2" outside. Had to disassemble the motor (1/2

job), and remove the old mast piece. I installed the new while the motor was apart (also 1/2

), reassembled the whole mess, and voila! Works great.
