Ordering piston rings for 5.9 what size do I need

Thanks guys, it's a 5.9 Magnum, stock bore and pistons. and I had a chance to get online here at work to check it out. The Magnum does use metric sizes, 1.5, 1.5, and 4mm, so just ordered a set from summit, along with an oil pan, and a ball type cylinder hone, cause nobody around here rents them.
