I have a 440 with 2" tti headers. I will get it on the lift this week and take some measurements. I have a fast ratio pitman arm to measure with too. I think the hard part will be the correct angles. But it is possible to measure.
Now the hard part. How can the parts be made? Machined solid steel? Where can the threaded ends and bushing be sourced? I could probably make something from tubular steel, but I don't know how to get it to mate up to the drag link, or get the bushing end for the idler arm. Opinions please?
