Glad you're not hurt and the damage isn't too severe.
The factory bolts are known for working themselves loose. When redoing the front end on my Nova stocker last Winter, I used these Moog offset control arm shafts and Energy Suspension urethane bushings. They have a large diameter stud and lock nut in place of the small factory bolt.
Global West makes a great setup and Afco has greaseable steel control arm bushings.
