does anyone know wut size screws will work to put a header on a .12 cvrx??? im so confused and its gettin frustrating. i tried the screws that came off my rustler's trx 2.5 and the screws fit the header but r too small for the engine. i tired finding it online and the screws that come with O.S. headers are 3mm so i went to a store and bought 3mm and they were the same size as the screws i had?! i dont get it. i also got some 4mm screws and they were too big. am i missing something here? doing sumthin wrong? i have no clue. ive had nothin but bad luck tryin to put this engine in. some one please help!

well, i just went and looked at the holes for the exhaust screws in the engine and i dont think they r threaded. can some one plz tell me something????

nevermind....im a noob and feel stupid now , i found header springs on a website...ill go see if my LHS has them in tomorrow and if not ill order them
