To install with OpenIV simply replace these provided files.


carcols.meta carvariations.meta and handling.meta all go in:
  GtaV\mods\x64w.rpf\dlcpacks\mphipster\dlc.rpf\common\data

The civilian and ex police versions each have different handling, do not mix them up.
 
vehicles.meta goes here: 
 GtaV\mods\x64w.rpf\dlcpacks\mphipster\dlc.rpf\common\data\levels\gta5\vehicles.meta

Choose civilian or ex police version and replace the four provided "glendale" files here:
GtaV\mods\x64w.rpf\dlcpacks\mphipster\dlc.rpf\x64\levels\gta5\vehicles\mphipstervehicles.rpf


Credits for making and converting the model go to Carface and Esprit.
