Hi Dave. Certainly no offense taken; actually I appreciate your concern. The bottom line is, the radius rod itself would either bend or snap long before those grade 8 bolts give way. If the rod end breaks, double brackets would have no effect either way. Clevises are a viable alternative, but they are really no stronger than good quality rod ends. I guess it comes down to personal preference; anyone building a car should do whatever makes them feel confident and secure...
