The main concern is the input gear length and spline count matching.

This might help:

Spline count on an 89 should be 21 and on the 98 should be 23. No worky.

No. The 98 input shaft is 23 spline. Your 89 is 21.

No like if I take out the tcase out of the 98 and rebuild it with 89 spline and intake shaft so the spline match up would that work?
