might be irrelevant, but if you do need to swap out the axles to a fox body length axle, you can still use the sn95 brakes with a very simple mod. Uses a passenger axle from an Ford Aerostar, a drivers axle from a Ranger or Bronco II, and the calipers and mounting hardware from any SN95 mustang. I haven't done it, but I'm planning on doing it and have all the parts. Tony from Junkyard Doggs does a really good job of explaining how to do it. You can get the parts from a junkyard, or buy them new.
