Rainbow Six Siege - need help getting a model from it

[Tervel1337]

So I wanted to get the police car model from before the models update. It's actually the E3 Cavale from Watch Dogs and if I get the model I can add it back in. I tried ripping it with Ninja Ripper, resulted in broken mesh, 3DRipperDX, didn't work at all, and Intel GPA which manages to rip whatever the player is holding but nothing else. So I obviously tried digging inside of the game's files. I followed some ''tutorials'', used the tools provided, converted the .forge to .data and then to .dat and at that point I was in a complete loss. Any help would be greatly appreciated.
