There really wasn't much to it.
But, considering the factory method of attaching the LCA pivot tubes, even that "washer" with crappy welds was an improvement over nothing at all. The LCA pivot mounts didn't have a whole lot holding them in to begin with.
It's pretty easy to reinforce the K-frames though, and any reinforcement would pretty much be superior to anything the factory put out. I've done a couple so far, I do a seam weld around the entire edge of the K frame, go over all of the factory welds, and add gussets to the LCA, idler, and steering mounts. I also gusset the torsion bar anchors in the crossmember, as it seems that A-bodies in particular had pretty lousy welds there.
