You need to change the model file directory when you edit the vehicle/object, the directory needs to go to where you moved the new model files to. For example OLD MODEL FILES DIRECTORY: Modname/models/vehicles/ford_explorer NEW MODEL FILES DIRECTORY: Modname/models/vehicles/03 LA Police Something like that, but obviously wherever you placed the vehicle model/doors/wheels. This needs to be done to each door/wheel etc for the model you want.
