Stole another few hours in the garage and extended the box section that runs from the bulkhead to the suspension turret.  It is just tacked in place and looks somewhat neater in real life than it does in this picture.  Ready now to get the shroud back on and finish the clamps to the lower front section.  I am feeling quietly confident about this and hope that it helps to align the shroud correctly because I am keen to make some headway with the car.
