Wilwood's rear disc/drum backing plate brackets for Ford are made from high-strength aluminum alloy and use steel 5/16-24 clinch nuts for caliper bracket or accessory mounting. Offered for most popular axle flanges, these backing plates work with 11.00" through 12.19" one-piece rotors or 12.88" to 14.00" hat-mount rotors, providing a structural mounting interface for rear braking components on compatible Ford rear axles.
