Looking for a AWD tranny for my 95 TSi, what spline?

[98TsiAWD]

I have a 95 talon taht I need a tranny for, I have the transfer case etc, how do I check what spline transmission I need?

I found out from shepard its a 23 spline, so why on car-part.com when I search for a 95 tranny it asked me if I need 21, 22, or 23 spline? Ive never even heard of a 21 before.

I think the 21-22 spline ones were for the 1G... I am pretty sure there is only one for the 2G

NO such thing as a 21, 22s went untill 93ish then on to 23 till present.
