Just for the sake of conversation, the high pumpkin diffs are not the same
as the low pumpkin diffs. The gears are not the same, and if used in the
wrong application they will not be as strong. I don't know that this is an
issue for you to be concerned about or not, but my recollection is that the
Cherokees and the YJs have different D30s.
