I recently did the K frame in my Cuda, granted the car is still in peieces, however I did a consdierable amount of research on my front suspension. First stop is Firm Feel, look at thier welded K frame. I think they still do them by request, but anyone with a welder can do it. I welded up all of the seams but more to your point, I welded/re-welded up all of the steering box mounts. Most of them were merely tacked in place. The is enough bracing already in there (unless someone before was trying to lighten the car in the wrong place), however they need to be reinforced by welding all of them. The one spot the FF (and subsequently I) added bracing is behind the steering box mount which is hallow. it doesnt take a lot of metal to fill it in to create a very solid mount.
