Stop in for a cup of coffee

Decoding ford #'s is kinda weird.. they just randomly leave **** off the tag :)

If the rear is cheap it's a good starting point.. 9" tru-tracks (i think that's the name?) are pretty cheap....
Track Lock or Traction Lock is their limited slip. The step up is the Detroit Locker. Ford didn't piss around with it. If I'm not mistaken, they are the only one of the big three that used the Detroit Locker in production.
