I may be all wet here, but I'm thinking that that rear is from an Aerostar van. It has the ear for the upper link and the hanger on the snout for the vibration damper. If it is a ford diff, then the bolt circle will be 5 x 4 1/2. The best way to be sure of the bolt circle is to measure from the center of one stud to the outside of the one roughly opposite from it. This will give you the circle dimension. This method is for 5 lug only.
