Keep it and if you've got the ones from your motor mounts to the converter cover, keep them too...and if you haven't got them, get them! Your motor/trans/t-case are mounted in two places longitudenly (is that a word? you know what I mean), apart from the torque of your motor trying to twist the whole assembly like a big carrott about to snap, when you go over any big bumps or get any air that whole assembly will try to flex in the middle when it lands and the trans is only bolted to the motor at the top and sides by 6 comparitivly small bolts.
