I know how tou can make one with a broom stick or a wooden dowel about the size of the inside diamiter of the clutch or outside diameter of the front shaft of the tranie, you will have to do a little whittling on the end to make the pilot shaft on the end to fit the pilot shaft bushing / bearing, use your front shaft as a pattern to compare and to go by
it dont have to have the groves in it likes on the front shaft of the tranie just a good snug fit through the clutch disc , I use a grinder to shape mine .add just a little grease not much at all so it will slide in the pilot shaft bushng / bearing easy , i know your laughing but hey it works and easy to make when you can't find a line up tool
