@DarthPungz Im pretty sure you can just delete their names out of the file and the vanilla vehicles wont spawn at all, unless its set to spawn in an ambient scenario or in a mission. Replacing the yft and ytd will get your new vehicle to spawn but the game dosent know that. If you install an add on and then add the model name to the popgroups and the other files the game will know to spawn the vanilla and add on vehicles. I can upload my popgroups and vehiclemodelsets.meta files to show you what I mean if you want.
