Engine/Transmission (1994 - 1998) 241 dld and 241 dhd

I am trying to find out the correct number of splines for the dhd tranfer case in a 6 speed application. I have been looking for one of these transfer cases and they have been asking if it is 23 or 29 spline? Is this the input shaft spline or the output at the rear driveshaft? I searched the forum here and did not see this information.

29 spline input.
