I am looking to swap my 98 Chevy and have a rh47, I wnat to keep my push button t case which is a np243 will the rh47 bolt right up to it, and what will I have to do to make the speedo work?
NO match, just determine the right spline count for the application.. The next issue is the thickness of the gear on the adapter be it thin or wide and the gear tooth pitch and width, finally machining for length.Did the 241c and 48re splines match up, or did you have to make up special shaft? If they matched up, then that would be the way to go for Noa if he can stand a computer on the re!

Later 4L80 series used the 32 spline shaft, that is what was in my truck.There were 2 different 241C transfer cases depending on what transmission they went with. The TH350, 700R4, and 4L60e used 27 spline input and the heavier transmissions used 32 spline. The Dodge 48RE (A618) has a 23 spline output so I don't see that matching without an adapter.
