Need steering knuckle..

[Tsgs69400]

I am in search of a steering knuckle for an f-350 with 4x4.
I is the part which the spindle attaches to and the axle goes through. The axle is a 1992.
All local yards want to sell the entire axle only and Ford cannot find it.

Why are you needing one? I went through the same thing last year. Dynatrac was in the process of making them but they weren't in production yet.
My problem was the tie rod had wallowed out the knuckle. I ended up reaming out the knuckle and using Chevy tie rod ends which are the same taper but larger
