Well there are 2 8.8's. There is the 28 spline 8.8 that is found in most extended cab rangers, and in all 4.0 equipped ones. It is kinda hit or miss for the 3.0L motors. I have seen a couple with a 7.5 and an 8.8. But the 8.8 out of rangers bolt right in.
Then there is the explorer 31 spline rear end. This one requires some modification to fit in. It is considerably stronger than the ranger 8.8
And when in doubt
