home made k frame

Absolutely correct!

I saw first hand, the results of poorly engineered and shoddy workmanship in manufacturing K members from a company that is now defunct.

It was taken over and revamped by QA-1 .

I can't speak on the quality of their re-released products but it seems by the number of vehicles built with their components I have seen on here, they have improved.
I have a revamped QA1 k-member and although it is a nice piece, the mounting brackets for the strut rods are a few degrees off and not spot on. Otherwise, they are nice.
