I did originally think of using two spherical ball joints with a threaded rod. But once I realized how short it would be versus the cost of 4 joints, 2 bars, and all the boots, I figured the cost would be around 100-150 for quality parts. Plus you still need a bracket fabbed up. That's when I started looking at sway bar links. I work as a tech and see different makes and models daily so I knew it was only a matter of time til I found a decent looking one.
