Jeff for some reason the flash would not go off. Replaced the picture with a little better one.
The steering arm they show with your calipers look like they from George or his son. I have a set. I believe they are an investment casting of some type of stainless steel. If you do not have to bend them, they should be a bolt on deal. I think they told me to bend them, they will need to be heated cherry red. I am not sure on how they should be cooled. You would need to talk so someone that knows about those things. That being said parts of the arm is hollow. To me its a casting flaw. Tom told me all of them they have are like that . In some of the pictures below you can see the void in the bolt hole and where the tie rod goes in.
The arms are right and left handed. The single one above them is an unmachined forging. They can be machined to be right or left handed.
