Right, well you go to your ‘‘resources’’ file and you make a folder in there called what ever you want, you make another folder inside the folder that your made and you call it ‘‘stream’’ in the stream folder you drop the vehicle files, and than you make a __resource.lua thing in the folder that you made in the ‘‘resources’’ folder, than you go to the server.cfg and write in there ''start (name of the folder that you made) .And you are done
