Probably isn't bad if they're machined flat, and drilled and tapped. Mine were from a Colorado wagoneer, so no pitting or major rust. Just dusted them with a wire wheel, used the high steer arms for hole placement (you can see the raised bosses on the underside), clamped them in a machinists vise on my drill press. It did take a little work to get them square to the drill. I had to do both sides, since neither wagoneer knuckle is drilled. I also cut off the factory arm and ground it smooth.
