i downloaded it so i can help you. first you see those folders
swat is this model: m_y_swat.wdd
fat cop: m_m_fatcop_01
just type those names one by one in spark and click on the "model".wtd with contain textures and just replace all the texture with the same names. its really easy.
the hats and all that stuff need to be replaced in the pedprops.img (only for fatcop)
