Install: x64/dlcpacks/patchday4ng/dlc.rpf/x64/levels/gta5/vehicles.rpf
Replace the files of the standard police3 model with the files of the original model, then move the files from this archive to the same location.
With the help of Modding DLC by Albo1125, you can replace any other model. Rename yft and ytd files to the name of the model you need. Import police3 settings from vehicles.meta for your model. For the flashing lights to work correctly, use the 'sirenSettings value = "2" /' line in the carvariations.meta file.
