If its a standard item on the car it must be fitted,I cant see why you cant run the standard ones,I have complied one trueno and i dont think it had them at all and he passed.If its not stated on the sheet it should not matter if none are fitted..Dont know..Shit changes weekly down there
Damb there must be something that can work in its place,Ide just make it out of plastic and weld it together with a soldering iron.I had none when i went thru and passed but i dont have a trueno.
