One other thing to note.....the tcase on the 90 tranny will have a 26 spline (IIRC) output shaft......the tcase on your 96 will have a 16 spline (IIRC) output shaft. The tcases will interchange, so you won't have a problem there, or you can swap the slip yoke from the 90s driveshaft over to the 96s driveshaft.
