Carolines truck,
That's a great tech tip, Thanks.
I took a similar approach when I needed to narrow my tie rod, I reused the forged part on the left in this picture, although it once had the draglink end as part of the forging, I cut it off and drilled and tapped for a replaceable end.

I have welded drag links together to get the ends and lengths I needed, I feel that is a good solution in many cases. However, if you need one to be adjustable, then as you have done and written up in the tech tip would be the best approach.
