I have a wheelset of shimano xt m730 hubs from a 1991 to 1993 Gary fisher CR-7 evolution. I believe the spokes are double butted and were laced to an Araya RM-17 rim.

Which spoke nipple thread should I be looking to purchase? I am doing a swap to a pair of sunrims rhyno lite 32 hole. I did this already with an identical set with a gouge in a rim but this set of nipples is quite a bit rougher and I would like to replace them. I'm sure the rim choice etc is not important but I figure you can glaze over and let me know the standard spoke threading for an early 90s Japanese wheel.
