ba-10 to ax-15

I believe the BA-10/5 has a 21 tooth output shaft, and the AX-15 has a 23 tooth output.
You either have to get a transfer case from a 90 and newer XJ/YJ, or change the input shaft of the current transfer case to 23 tooth.

I'll give you this one for free (because I just know you'll get clobbered if you don't...)

Note that the Peugeot has a 21-spline output, while the AX-15 has a 23-spline. This requires that you either change the transfer case input gear or change the transfer case entirely. You can source a new input gear from either Novak or Advance Adapters, IIRC.

Same stricture if you go with an AW4 - get the 21-spline AW4, or a 23-spline input to go with your AW4. You'll also be needing a TCU - but the harness plugs should be there (I think.) There may be some programming differences between the A/T and M/T ECU, and you will need to change the TPS.

If "automatic" operation isn't important to you, you can omit the TCU in favour of BrettM's AW4 shifter, and you probably won't need to change the TPS, either. However, you will need to keep track of what gear you're in and stir your own slush if you go that route (just without the clutch pedal, and only four gears.)
