If you mean line up the drive plate, with the driven plate, with the spigot bearing, you need to get a mandrel. It can be an old gearbox input shaft or a proper one from a motor accessories shop. One end of it need to have adapters that will fit your spigot bearing and the sliding bit needs to be the size of the hole in the drive plate. They usually come with lots of adapters.
