14 bolt spindle thread problem

[Americanrider]

I munched a outer bearing on my 1985 K30 this past weekend. Upon removing the spindle retaining nut and what was left of the bearing race I damaged some threads on the spindle. Now I need to find out what the thread size is so I can find a thread die and clean them up.

After looking through the Pirate4x4 tech site [The 14bolt bible] all I found was this pic and the outer dia. I have tried to clean the threads with a thread file but they need more help before I can put another spindle nut back on.
