You don't need a tool to align it, I've done tons of clutches and never used one and never had any problems, Just make sure that the splined part of the friction plate is in the centre of the diaphragm springs on the clutch cover, just make sure you are looking sqaure on to the clutch and when it's tightened up you will see if it's in the middle, Only takes seconds to correct it if it's not in the centre Gary
