If I may suggest a few things I would address with this build, check the LCA mounts in the K member. They are notorious for separating from the k-frame. … Gussetting helps bigtime. Please post some pics of your project. We all would like to see em!!
Here’s the gusseted k-frame. I started with torching the seams and sand blasting. I popped the two halves open and burned more grease out. Finally got tanked. I used the Firm Feel gusset kit.
The torsion bar sockets are also going to be welded on the inside of the torsion bar crossmember. I will cut the floor open to access it.
