On W123 cars the special sunroof tool is located on the left plastic trunk liner. There is a unique slotted hole in the plastic liner which holds the Tool. If I remember correctly the tool is sort of an anodized goldish color. The W123 wagon does not have a sunroof motor as the sunroof is a manual crank type. Yes, the hex shaped shaft which is part of the sunroof motor is the manual crank to turn the motor.
