I was wondering if a late model transfer case 91-96 would bolt up to a 89-90 5-speed? I was wondering this because i can't find lower transfer case gears for the 89-90 sidekick only 91-newer. iwas wondering the reason for this? Thank you for any help.

I have heard that the 89/90 tcases are a little different on the inside than the later ones.  I have not verified this info personally though.
You can use a 91-95 tcase in yours.  In 96 they changed the rear output shaft spline to a coarse 16 spline (compared to the finer 26 spline).  If you have no other options, you can use a 96 and later tcase and either swap the rear output shaft out, or use the later slip yoke that fits the later output shaft (all the trackick driveshafts used the same ujoints, so you can just swap the slip yoke portion of a later driveshaft to your driveshaft).

there differences in the internals of the early t-case.   stan
