We report $^{29}$ Si NMR spectra and Knight shift measurements as a function of applied field orientation in the (001) basal plane of URuSi. Observed linewidth oscillations confirm the in-plane 2-fold ordered domain state observed in recent magnetic susceptibility measurements. Analysis of our linewidth data leads to the estimate for the 2-fold intrinsic (mono-domain) susceptibility anisotropy in the basal plane, a value times smaller than that obtained from recent susceptibility measurements.
