The last thing to do to the control arms was weld in side plate supports. The arms had a tendency to bend and collapse at the corners. The Trans Am Javelins were actually the first to employ this modification! Both sides of the arm had a single plate welded in the corner, top and bottom. The ends are left open on purpose. After all the welding was done, I did some minor grinding back, checked for any cracks, and declared them ready for primer and paint.
