The welded k frame is a key piece, do not pass go, do not buy expensive parts or put in the hotchkiss products unless you weld the k frame and box the steering mount.
I have no real world on track experience to dispute or confirm the above, but since I have seen many chopped/cutout/sectioned K members on moparts for clearance/oil pan issues, and none of them IMO retained the full strength/rigidity of an OEM K member, dose that mean they all went backwards in performance, accepting most were 1/4 mile apps?
He means weld the K frame to the frame rails. He doesn't mean modify the K frame in any way.
Very common/proven effective modification since at least the '70s that I'm aware of...maybe earlier that I have not heard of
