If the pilot bores in the crankshafts are different sizs, then measure the ID and OD you need and find a bushing/bearing that fits.
You need that bushing/bearing - a shaft has to run on two bearings in order to run true - if you don't have a relatively tight-fitting pilot, you'll end up munching your input shaft bearing rather quickly (due to shaft wobble. Unless you're using bearings with spherical races, shaft wobble is going to kill bearings!)
