The tranny to driveshaft is coupled with a chunk of rubber with 6 holes in it. This takes 3 from the tranny and the other 3 to the driveshaft. (has a name) It is soo easy to adapt. I have already adapted it to a NP 203 transfer and, with the 29 year old 116 engine, use it on a gm suburban to plow snow. In 4 wheel drive, low range, I have folded the plow in two. The torque on the diesel is incredible.

Have you ever heard of a M46 OD box in NA?
