Note for Mustang II customizers: Hot-Rodders often use the Mustang II front suspension assembly to replace old solid axle setups, so many custom tubular A arms and shock combinations are available. The Mustang II spindles use the same bearings as the Granada so its 11" discs can be swapped with a custom caliper bracket. Check Hot-Rodder or Street-Rodder magazines for sources.
Note for Mustang II customizers: Rear disc brakes are available for Ford 8" rear ends.
