Who makes a Early-A Narrow Aftermarket K-member

I tell you what I HAVE seen.....I've seen some K frame flex in a B body with manual steering. I'm sure you could measure flex in mine with a dial indicator. That's why I'd like to see how to reinforce in that area. Since I plan on keeping this car and I don't plan on a k frame "upgrade" I wouldn't mind seeing how to upgrade "what's there". I'm sure I could look at it and figure it out, but I'm always open to ideas.

Ultimately K frames are pretty simple to beef up. It's a box and a poorly constructed one sometimes. Mostly you're just doing what the factory should have done.
