I did a clutch and flywheel on my 93 mustang this last weekend. Got it all togethor and have a slight vibration that feels likes its from the engine. it increases with rpm and does it moving or standing still, and with clutch pedal in or out. Im thinking the flywheel was the wrong balance, misboxed or made wrong. Quetion is how bad would it vibrate if it had the 28oz. flywheel in it? Would it be like "Oh My god this thing shakes and something is wrong" or "hmmm somthing dosnt feel right".
