  In earlier work we analyzed an abelianized model in which a gauged
Rarita-Schwinger spin-$\frac{3}{2}$ field is directly coupled to a
spin-$\frac{1}{2}$ field. Here we extend this analysis to the gauged $SU(8)$
model for which the abelianized model was a simplified substitute. We calculate
the gauge anomaly, show that anomaly cancellation requires adding an additional
left chiral representation $\overline{8}$ spin-$\frac{1}{2}$ fermion to the
original fermion complement of the $SU(8)$ model, and give options for
restoring boson-fermion balance. We conclude with a summary of attractive
features of the reformulated $SU(8)$ model, including a possible connection to
the $E_8$ root lattice.
