I already called advance adapters they said they couldn't make one to the allison or the zf6. They sinch my tcase has a 32 input spline and the allison and zf6 has a 29 spline they couldnt make a stub shaft to adapt that. Which doesn't make since it dont sound that hard just a space and a stub shaft but o well. My transfer case has the excact bolt pattern as the allison and zf6.

btw I live in ohio
