Doesn't matter that they are both 231j, just means it's a 231 from a 'j'eep. The Cherokee 231j likely has a 23 spline input if it came from a 4.0L auto, yours is a 21 spline input because it's from a 2.5L 5spd.
I know the 231j inside and out, I build a lot of them for jeepers who have either broken them or are upgrading from a full--time transfer case to the 231j.
