  We probe for operators occurring in the APQCD(``abelian-projected QCD'')
action by evaluating abelian-projected $1$-plaquette spectral densities in pure
gauge $SU(3)$ fixed to maximal abelian gauge. Couplings $B_{APQCD}(q,L)$ are
extracted from the spectral densities for each representation $q$, $L\times L$
plaquette. While APQCD is dominated by a $q=L=1$ resonance, we also find
evidence for weakly coupled $L=2$ plaquettes. Moreover, since $B_{APQCD}(1,1) >
B_{QED}(1,1)$ even if $\beta_{QED} > \beta_c$, $L>1$ plaquettes must be
significant since APQCD is confining.
