How to upgrade my spindle on a 1996 ford ranger 4x4? With the Dana 35?

So I was going to replace my wheel bearings then noticed my locking nut was damaged and also the threating on the spindle. I have visited many junk yards and they do not have spindles. So I was wonthering if any one knows where I can buy one or just upgrade to after market spindles?
