Looking at pictures and wording to left side, you install rivets w/washers (must be like a spacer between a-arm and guards) down through guard and install with u-bolts around a-arms, with nuts and washers exposed on bottom side. appears to be a no drill install. Maybe someone else can confirm this.Yea! More options. Do you have to drill into the arms to install these? The text is blurry when I blow it up.
