I'm working on a fork conversion right now and need 3 stem nuts. None of them have commonly available threads. Let's see who can do the best internet search. Oh and if I knew what the stem was for, I'd already have the parts (I don't). It is for a yz450 but is aftermarket, likely Pro Taper or Ohlins. bottom nuts (qty 2) are M30x1.25 Top nut is M26x1.25 I ordered both of these nuts from a roketta parts site but the nuts that arrived had such boogered up threads, they wouldn't fit. Thus, the search continues. Your help is greatly appreciated.
