231 input gear swap.. Help please

[Blue88Comanche]

I just bought a AX-15 for my MJ and need to swap the input gear on my 231 from the old 21 spline to 23... my old transmission was a BA-10/5..

 

is this the part i will need to swap to get mt TC working with my new tranny?

Maybe, maybe not. The cut of the gears changed in 94. If it's from a 93 or older, it will fit in your transfer case, but I don't know if it's the correct length for behind an AX15. If it is 95 or newer it won't fit. 94 would be anyone's guess.
