There shouldn't be a problem, just use a 23 spline transfer case with the tranny, the ratios are all the same for the t-cases, doesn't matter about the spline count. If you don't have a 23 spline t case to go along with the tranny you can use the 22 spline one, just swap over the 22 spline input shaft over to the newer tranny.

The only other thing I can think of is you may have to use the 91-94 shifter cables with that tranny, or you can just swap over the bracket on the tranny that holds the shifter cable, and look at the shifter arms on the tranny, one of them might be longer or shorter, and you may have to swap that over if they ae differnt.
Not a big deal though, you should get it to work.
