could anyone tell me what to look for to determine if a rear is a 9 incher ? Also , what do I look for to tell if it is a non-slip ?

Ford 9 inch you CAN NOT get a deep well socket on the bottom to nuts of the differential or pumpkin. As far as non slip. I think if you jack up the rear and place a block under one wheel to keep it from spinning. And you should be able to turn the other wheel. Hope that helps.
