i don't think the nippondenso alternator i used will fit with the march serpentine belt kit. the pulley on this alternator is a bolt on. also this alternator is longer than the original and will need to be spacer forward. i run a single belt setup even with power steering. the original march kit used 2 belts. if your not running power steering it might work but it might also mess up your supercharger pulley alignment.
