Ok so theres two studs that come out of the heads on a gt for the engine mount. Do i put both them same two in the GTP heads? Im asking because i cant find a nut that will fit so i can tighten my supercharger tensioner up to the bracket. Also are the E.G.R bolts m8x1.25 in size? The ones that connect to the downpipe and LIM. Please help id really like to get my car done soon its killing me.
