Angular distributions for pion-induced double-charge-exchange (DCX) reaction have been measured at 164 MeV on the T=0 target nuclei ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$, ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$, and ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$. The data are compared to calculations using the Δ-nucleon interaction model with realistic wave functions and πNN and ρNN form factors deduced from fits to previously published DCX data on ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$. The calculations reproduce the general shape of the angular distributions and the absolute magnitude of the cross sections to within a factor of two.
