What is the correct Getrag 360 Spline Count?

I have a Dodge W250 1993 5.9 4WD Manual Getrag 360. What is the correct input shaft (spline count?) for the Cummins Diesel 5.9 with a Getrag 360 4x4 3/4 ton?

The input shaft on the transmission is 1.250 10 spline. The transfer case behind the G360 would be 29 spline. If you need parts or a replacement unit give us a call toll free 888-824-2012
