Set your AD244 alternator into the mounting bracket and install, but do not tighten, the outer bolt. Note how much material will need to be removed from the alternator mounting bracket. Flip your alternator out of the path of any cuttings and remove just enough material elongating the original alternator hole to be able to install your new bolt through the AD-244 mounting hole. Note: You could use a smaller diameter bolt and not remove any material. Your choice.
