1959 Left handed thread spindle nut

[E Dorado]

Would anyone happen to have the reverse thread 3/4-20 castle nut?
Or is it possible to replace with right handed spindle from a 1960?
By the way, converting to disc brakes

Thanks in advance

  I don't have any spares either, I'm actually short one from misplacing it somewhere. I am going to eliminate the problem by using a right hand spindle on my 56, since the only difference is the threads. The steering arm bolts to it, unlike newer models that have it all forged as one.
 I believe that the 59/60 spindles also bolt to the steering arm, so they should be able to be swapped without issue.
 I'd have to go look at my 63 parts car to double check that though. If it has bolt on steering arms to the spindles, yours certainly will as well.
