Ford 8.8" Rear... Should I do it?

Yeah like said those Explorers have 31 spline axles. The 31 spline differentials have a bigger cross shaft then the 28 spline diffs. Those are some really strong rears. And they are all over the yards. A pick and pull not far from me its $69 any complete rear, you gotta pull it, but brakes are extra. But still dirt cheap and the Explorer and Ranger 8,8 rears are easy to find. Mustang rears those are always gone.
