Can anyone confirm or deny that the 6L90e 4wd 29 spline output is the same spline diameter as the 29 spline NV4500 output?

Looking at options to put a 241 case behind a 90e and there weren't any OE configurations that way, but I found some Dodge parts that might work for the application. I don't have access to the back of the 90e and I have no friends with a 4500 to measure
