The nice part about the IH TF-727 is it was used bolted to a Dana 20 and special version of the Dana 300 transfer case. The drive gear fro the transfer cases use a unique spline count, so you need the drive gear with the transmission. You could in theory use the output shaft, adapter, and drive gear from an IH TF727 in an AMC TF727 to bolt a Dana 20 to one. AMC TF727s come with the New Process bolt pattern only.
