  We calculate the two loop correction to the quark 2-point function with the
non-zero momentum insertion of the flavour singlet axial vector current at the
fully symmetric subtraction point for massless quarks in the modified minimal
subtraction (MSbar) scheme. The Larin method is used to handle $\gamma^5$
within dimensional regularization at this loop order ensuring that the effect
of the chiral anomaly is properly included within the construction.
