Ok, so for starters I've tried to install the Impala that Jeff used as an example, It was a replacement for the police2 slot. I looked at all the readme's and did what they said; The vehicles model and textures went into x64e>levels>gta5>vehicles. I replaced both the ytd and ytf closed OpenIV, opened it back up and opened police2, The impala is fully modeled and the textures look proper. Next is the carvariations the read me says to go to:GTA V/update/x64/dlcpacks/mpchristmas2/dlc.rpf/common/data and replace the current carvariations.meta with the one provided in the mod. step two done. that should be it for the impala right? I don't care about the liveries right know as it comes with some. The only issue is when I load in, and use simple trainer to spawn police2, its still the default car. I really appreciate the help.
