Is my lower control arm toast? With Pictures!

I started rebuilding my lower control arms and got the bushings out to put Peter Bergman's delrin bushings in and this is what it found in the bushing bore...

It looks like a previous owner did not use the washer welding method and really messed up the bore both getting the old bushing out and replacing it. Is the whole arm toast? Should I just grind the galling smooth and install my new bushings?

If it's toast, does anyone have a drivers side control arm they'd like to donate to my cause? If it is going to cost very much to replace it, I'll probably just cut my losses and buy QA1 lower control arms. I'm just glad I hadn't already welded the reinforcement plate on it.
