At sixes and sevens, turn to her for direction (4,5)

Ross

I believe the answer is:

'direction' is the definition.
(I've seen this before)

'at sixes and sevens turn to her' is the wordplay.
'at sixes and sevens' is an anagram indicator.
'turn'+'to'+'her'='turntoher'
'turntoher' anagrammed gives 'TRUE NORTH'.

'for' is the link.

(Other definitions for true north that I've seen before include "In the direction of one of the poles", "Position of maximum latitude", "Pole", "rarely needled when on the move", "Direction aligned with earth's axis".)

I've seen this clue in The Telegraph.
