Lower b/j to spindle nuts/bolts

[FSHTAIL]

Greetings everyone,

  I had a question and it concerns to the lower ball joint bolt into the spindle, are there just a nut and bolt holding them together or are there supposed to be washers?
Seems odd not to have any washers on at least the bolt side of things.
I'm planning on doing what Cuda Cody did with the black oxide treatment, the solution is on its way. 

73 Cuda if it matters.

Thank you

No washers...

Yup, no washers...the factory bolts typically had a castle nut with a cotter pin, replacement bolts used a lock nut like shown in your pictures, either will do the job just fine
