For those Holden HQ-WB and LC-UC Torana owners who wish to upgrade their early Holden brakes while retaining the factory HQ stub axles. Aeroflow Performance has designed these front brake caliper dog bones to suit the Wilwood brake kits. They fit both the 11-inch and 12-inch Wilwood brake kits or the billet Dynalite/Dynapro lug mount calipers. New high-tensile bolts and washers/shims are provided for safety and security when installing.
