Script that automatically detects and can load add-on vehicles, instead of needing to type the names yourself.
Download the ScriptHookV SDK and extract its contents to ScriptHookV_SDK.
Clone this repository to the same folder ScriptHookV_SDK was extracted so you have ScriptHookV_SDK and GTAVManualTransmission in the same folder. If you get build errors about missing functions, update your natives.h.
Clone my GTAVMenuBase to the same folder you're gonna clone this to.
