Mine carried a load of wood too get the wood burner goin to keep my house warm

So i picked up a real clean 2wheel drive 86 comanche. has 2.5 in it I want to do the 4x4 swap since the body and under side are spotless. My question is what kind of a cherokee donor should I be looking for? my comanche now is a 4 speed id like to keep it a stick but a speed would be better. How is this 2.5 in the 4x4? thanks
