Most 4X4 Ford rangers & Bronco II's have 8.8 And some have posi's in them with lower gear ratio's than the Mustangs.....With 5 on 4 1/2 lug pattern. They also were leaf spring mounted, they are easier to "clean-up" to use for 4-link.

The down side is the flange mounted rear yoke on the driveshaft so snag the drive shaft also.
