Yeh thanks Dodgeman, excuse my lack of posting skills That is first & reverse you see in the extension housing.
For rally use the dogleg gearbox also has the major advantage of the first & reverse gate being inline. This allows you to more effectively remove the car from any "dry bog" situations by driving the lever up and down the gate quickly whilst droping the clutch. Much quicker than using the conventional shift pattern. I often wonder if this was a deliberate consideration when Nissan were developing their rally option boxes because its a great application of the dogleg pattern and can mean the difference between parking it for the day or finishing the event.
