Transmission 1g to 2g- IMPORTANT

I got a 1995 tsi awd. The tranny went out and it sat for like 3 years at a car lot before i got it. I am paying it off and bought a tranny for it. But the stock tranny was a 23 spline. The one I purchased was a 22 spline of a 93 talon. Now i got my tranny and am waiting on my case that is also 22. Now I cant seem to figure out if my driveshaft is gonna slide on to my new transfer case or if anything would be a problem. Some say they are universal and some say they arent and I need new axles. ** DOESNT ANYONE KNOW
