JW51,
Just as you are suggesting, a few years ago I used the Speedway 11/16 Inch Raw Tie Rod/Drag Link Tubing and used male L&R ford rod ends , that way i just bought the RH tap & cut/tapped for a adj drag link. There was just enough meat for a race shop to taper ream the steering and pitman arms. It is holding up well.
BTW: when i thread tapped inside the cut end i started with rod 1" longer than i needed, even using a proper tapping fluid, it turned out a good move as the first bit of the tap process (finding straight) alignment left those first threads looser that desired, had the 1" to trim off so threads were a good snug fit, ie: dont tap too deep........
In reality you don’t get much adjustment as you want a lot of thread overlap inside the rod.
The one downside to the speedway rod is that there is no ideal way/place to put a wrench on it to tighten the jam nuts (to keep both ends aligned). Thought about welding a drilled out nut over the end to wrench on but did not.
