Aftermarket part rant
So, after my anger and frustration subsided, I went about fixing my control arm problem. My ball joints arrived and fit fine. I decided to try and use a stone hone too increase the size of the hole for the bushings. Fortunately the metal where the bushings mount is thicker than my original sbj arms. I was able open the holes up to the same size as my original sbj arms.

I'm still pissed that a relatively simple job became so much more involved just to fit new bushings.
