Don't worry, you found it. The words I was after were Kupu-Kupu Malam, which is the name of the workshop that made this kit, located in Yogyakarta. The reason I found that part interesting is that the translation of this name is "Night butterfly", and in Indonesian language this is a common euphemism for a "streetwalker", i.e. a prostitute. So quite an unexpected choice of name for a car customization shop. Well done.
