Need thread size and pitch for the prop nut on a Ryobi 31cc engine

Any of you conversion guys know? I misplaced the nut, and I'd really rather not take the plane to the local hardware and try different nuts....might get a reputation of being a little on the crazy side[X(]

For the old inverted Ryobi's, the long shaft ones were 3/8-24 and the short shafts are 5/16-24

Thanks a bunch. That narrows it down quite a bit. I'm pretty sure it is a long shaft.
