They all have the rockwell t-221 transfer case with 3 drive shafts. One of the shafts might be for a pto. I think the k-20s had that option.
the fourth shaft would be coming from a pto, not for a pto but for whatever it has to drive. that means that it has a pto on it.
it should have a t221 unless someone upgraded it to something else
