The transfercase rear output didn't change until 99 when they changed platforms. The webbing on the case is different and the rear output is the larger shaft with fewer splines. If you found one older than that with the coarse splines it just means that someone swapped for whatever stupid reason. The transmissions are identical except for the 5th gear switch that the early 8V 1.6s used for the EGR valve.
Even the transmission from a 1.8 will bolt up, same bellhousing pattern, not sure about the depth of the bell though because the 1.8 might have a thicker flywheel like the 2.0 did.
