Uuuuuuuuuuuum, yes it sure will work if the following conditions are met:
1. You currently use a 23spline tcase, then it's a no brainer direct bolt-in.
2. If you have a 22spline tcase on the GVR4 there's a simple fix. Simply remove the 1G trans' 5th gear cover, slide out the 23 spline output shaft, and slide in the 22 spline shaft from the trans that you already have. Bingo, you can now use a 22 spline tcase on your "23 spline" trans.
