"Anyone have a 97-98 with 4R100 and AWD/2hi modes"
Doing a little custom build on a truck, and trying to gather some information. I know the 4r70 had the 28 spline output shaft to the Tcase. I am looking for a transfer case with ESOF AWD, 2hi, 4hi, 4lo. That will bolt to a 4r100 (the pattern is the same) just worried about spline count and lenght.
