Replaced failed strutrod poly-bushing today - Took video of working suspension

The K-member is not reinforced at all unfortunatly.
It was nicely powder coated when I bought the car.
I just beefed up the steering mount pad which gave a slight noticable improvement.

I might be looking into welding some gussets to the flanges in the area of the swaybar mounts.

It's a Hellwig swaybar.
Here it is some 5 years ago when it was brand new and just installed;

Thought that sway bar looked familiar! :D

The steering box reinforcement is a great addition, but I'm sure you know there's some additional stiffness to be gained by doing the full seam welding treatment. On mine I also gusseted the LCA pin mounts. I didn't gusset the strut rod mounts, just because I use adjustable strut rods and they use a large metal pillow blocks on both sides of the K frame to begin with, already spreading the load over a larger surface area than stock.

Your video does get me thinking though about those sway bar mounts. The seam welding probably helps some, but there's nothing really supporting that flange where they mount.
