He mentions using a torx head screw and vice grips. Does anyone know what size screw? (I think its T15 but I'm not sure). I've seen some posts where its said the screws from the throttle body will fit. If you use one of those it's better to use a jam nut than vice grips so you don't destroy the threads. Also, if you have one, an E4 socket is the correct size. (Snap-On has one for $14.00).
