No pictures yet, but I did end up drilling out the bolts. I found some new flanged bolts, and new flanged locking nuts. I ended up installing them so the bolt comes up out of the control arm, and the nut is threaded down onto it. I found it easier to tighten this way with the shock installed as I could grab the end of the bolt threads with some pliers while using a wrench to tighten the nuts. I also used blue thread lock on the threads.

It all seems solid. I will have to check them after a bit of driving to make sure its all held up well.
