Keep hearing about frame twist with 440s

I have installed my homemade frame connectors on many of my builds. I am not a road racer, drag racer or pilot of top fuel dragster just a guy driving down country roads. I will keep on welding them in. If someone buys my car and don't want them, then cut them out!! lol

got some pictures of how you did that?
i plan on doing my duster with just 3X2 laying on the 3 inch side, but im not sure how close to the fuel lines that would run
