AX15&NP231 from Cherokee

My buddy is looking at doing an AX15 swap. He found an AX15 NP231 combo from a Cherokee that the seller says shifts good, and the TC has an SYE. MY question is for the clocking on the NP231 though. I have heard that if you were to bolt an NP231 from an XJ to a YJ AX15 you would have to drill new holes to adjust it so it is not at an incorrect angle. It was a long time ago I heard this, but never checked to see if it was true. If you get the combo complete from the XJ and swap the Dakota Bellhouse onto it for the 2.5 will everything else be fine? It is not the end of the world if the angle needed to be change, I can do that, but I was curious if other than the belhouse it is just a bolt in swap.

As far as putting an AX15 into a YJ with a 2.5 I go that covered and have already done it myself.
Complete rebuild axle/engine/everything swap in progress: Building stock width 44's with 302 from 01 Explorer. Motor has GT40p heads, Cobra Intake, and truck cam. Running A9L EEC IV stand alone engine from late 80's-90's Mustang GT. Big Bearing NP435 married to NP205.
