Thanks for the help @OfficerLavery however none of the solutions work BUT! @StarWolf123 has figured out my problem without him intending to, so thank you for that! Now I will install your textures. Thanks again.
I cant get the model to work properly, the textures are misplaced and the livery is purple, i dont understand why :/ I replaced the police files in vehicles.rpf but not luck for me... Any help?
