  Knowledge of the shape of dark matter halos is critical to our understanding
of galaxy formation, dynamics, and of the nature of dark matter itself. Polar
ring galaxies (PRGs) --- early-type galaxies defined by their outer rings of
gas, dust and stars on orbits nearly perpendicular to those of the central host
--- provide a rare probe of the vertical-to-radial axis ratio $ (q_{\rho} =
c/a)$ of dark halos. We present a Fabry-Perot velocity field for the H$\alpha$
gas in the kinematically-confirmed PRG \gal. By comparing ring orbits evolved
in a generalized mass model to the observed ring velocity field and morphology
of \gal, we conclude that $q_\rho \sim 0.5$ and rule out a spherical geometry.
