Granada 5 lug spindles
The Granada rotors are a one-piece unit. You didn't specify what year mustang you wanted to put them on, but if you are using the Granada calipers, you will need Granada spindles as well. Even if the bearings were the same, the caliper mounting hardware is only on the Granada type spindle. If you were wanting 5 lug wheels on a mustang II, then look in a street rodder magazine, you'll find at least a half dozen companys that sell direct bolt on 5 lug rotors for mustang II's, and they are inexpensive.
