Jeff, your welcome;
The GM version, 2 wheel drive NV-4500 with its Bell Housing provides the needed clearance to run a shaft drive with a Chelsea Series 352 Bi-Directional PTO for the MU-2 winch. The Centerline of the PTO output is 3.5" off the side of the NV-4500.
There is room all the way to the front for the shaft. This was not the case with the Dodge Version NV-4500 which is why I went with hydraulic drive on the Carryall and M37. For some applications, the GM NV-4500 makes for a easier install as the Starter is on the passenger side. This eliminates real estate problems with the Saginaw PS Box. Dodge application NV-4500 mount the starter on the drivers side and require setting the Cummins 1.625" to the right for clearance with the Saginaw PS Box. However, if you want to use the existing NP-200 T Case in its OEM location, Only the GM 2 wheel drive NV-4500 with the SHORT tail shaft will
work and then you have to set the engine much closer to the radiator. I still had room for a electric fan between the radiator and cummins.
My GM, 2 wheel Drive sits at 7.5 degrees tilt. With the GM adapter at a tilt, you can either set the Cummins level or the tranny. I like the looks of the engine level otherwise it looks like you dont know how to count little marks on a measure stick to set it level LOL. With that said, the rear mount surface on the NV-4500 is also at a angle. I used 4.0" wide x 5/16" heavy channel. Each side bolts to the frame using (4) .500" grade 8 hardware. The round isolation mounts you see in the picture are NAPA 602-1258. They are 3.0" in diameter x 1.250 thick. Each side has a 7/16" stud for mounting. The riser coming off the channel/isolation mounts is also 4.0" wide x 5/16" channel heavy wall. The height of the riser is determined by engine position. Since my T Case is at 7 degrees down, my engine/tranny must also be at 7 degrees down so they are parallel for the intermediate propeller shaft. Its really a dirt simple mount, but very strong.
With the torque your planning, I would consider nothing less than a NP-205 T Case married to the cummins. A Married combo eliminates the intermediate propeller shaft, is much easier to establish correct angles as the engine/tranny and T case are all solid. The only reason I went divorced was that I wanted to keep the NP-200 divorced T Case for the time being. I plan to drive the centered rear axle off the center Ebrake drum. At some point in the future, I will convert the NV-4500 and marry a NP-205.
Please email me if you have any indepth questions, I will help you in any way possible. If I am lucky by July the snow outside the shop windows will melt ha ha ha
