3. Yeah, they look sweet, but more importantly, these new TIG-welded tubular control arms from Classic Performance Products (CPP) are much stronger than what was put in the ’67 over 40 years ago. The arms are made from 1.25-inch, 0.120 wall DOM tubing and have thick 1.5-inch, 0.188 wall pivot barrels. This ensures the pivots stay true even under stress. They come preassembled on new billet chromoly 4130 cross shafts and pivot sleeves.
