67 Barracuda Big Block K frame keep it or change it ??

I've read the 67 K frame for my 383 Barracuda was one year only, and can't add power steering ??? I've looked into QA1, but do not like how weak/flimsy it is, but love the idea of easy access to everything. Anybody switch to a new tubular K frame, and drive it yet? I want to add: headers, power steering and brakes. I assume finding a 68-69 Big block K frame is what I need to do??

Not to hijack, I am looking for clarification.

This is the first I have heard of the QA1 unit being weak and/or flimsy. Can you expound on this please? I have the QA1 K member and suspension pencilled out for my build.
