does anyone know if i can swap cases with a 1/2 ton with my 3/4 ton??

i found a push button transfer case out of a 97 1500. i was wondering if i can get it split it in half and swap all my gears and shafts into it? i remember you could do that with the 700r4 and the th400,,

If the case is an NP243 with a 32 spline input, you should be able to put it in there just fine.
I don't think you'd need to split the case and swap anything.
I am NOT 100% sure of this, but I am fairly certain. :)

I don't think the gears etc changed between 1/2 and 3/4 ton trucks. It *should* be an identical part.

the half ton isnt a 32 spline,, my 3/4 ton is,,, the case one my 3/4 ton is cracked... i just want to use the case of the 1/2 ton transfer case,, not the gears or shafts,,, i want to put all the gears and shafts out of my 3/4 ton in the case of the 1/2 ton,,

i guess i just need to to know if the outside case is interchangeable,,,

just to let everyone know,,, what i did was

took the transfer case from a 97 1500 4l60e and split it apart,,, (27 spline input)
split my transfer case apart (32 split input)(98 2500 4l80e transmission)

swapped the 32 spline input shaft and the "like spider gear" set up,, (im not sure what it would all be called) into the transfer case from the 1500 truck
also put my speed sensor in as well,,,

put the case back together and put it in my truck... took the truck for a ride and have no issues... 27 spline to 32 spline was a success!!
