How do I change a broken bolt on a control arm of a 1989 chevy caprice? on 1990 Chevrolet Caprice

The bolt on the inside of the control arm bar broke recently on my caprice. I was hoping I could just replace the bolt but after looking the area over it seems impossible. The problem has caused my driver side wheel to slant inward and steering has become tight. I stopped driving it the moment I heard the bolt break.
