Off-road design makes an adapter. I had them build me a np205 with the 32 spline input. They sell a kit to convert the older 8 figure style as well. That’s the cheaper route. If you do use a 2wd trans make sure it has the full spline output shaft. Then you can just cut the shaft dawn to adapt it. There is also a small plug in the rear of the case that had to be replaced. It fills the tail housing with fluid when it’s a 2wd. Be sure to replace that with a plug. Gm makes it but I don’t remember the part number.
