hole where front strut rod attaches to the K member problem

I would fill it and get the shape back OR find a new K-member. I bought a 73-76 K-member out of a wrecking yard a few years ago that the original welder forgot to weld one of the reinforcement plates on. It wound up tearing the thinner metal of the k-member body. I got it fixed, but it was a bit of work. Fortunately the hole was still round.
