The spark plug / index pin tool! I forgot that one.

On the clutch disc however, i didn't use a clutch alignment tool. By the time i was putting the trans back on after my rebuild I was just about sick and tired of ordering parts and tools so i left the pressure plate bolts just slightly loose (but tight enough to have friction on the disc), eyeballed the disc centered and then put the trans on until the input shaft was in the pilot bearing. The input shaft aligns the disc when its inserted so then i just removed trans and tightened the pressure plate bolts to spec.
That's an old trick i learned when I was a teenager and very hard on clutches! I probably changed the disc or flywheel every 6 mo in my old 240sx back then.
