Usually when I install vehicles I make a mods folder and put the vehicles in the latest patchday which has always worked until now. I put my vehicles into mods/update/x64/dlcpacks/patchday23ng/dlc.rpf/x64/levels/gta5/vehicles.rpf. I replaced police, police2, police3, police4, sheriff, and sheriff2. The only one that has been changed to the new model was police. Any help would be great. I do have the asi loader installed from openiv.
