I assume you want the 5 speed for the overdrive.

I am at a loss to think of a 5 speed that goes between the stovebolt bellhousing truck and an NP205 because an NV4500 does not have the right mounting pattern. I think you could put a T5 in front of a passenger side drop NP241.

I believe you could get an NP833 4 speed overdrive with an NP205 behind it in an early 80s 6.2 diesel 4x4.

Give me a night to think about this. I am thinking AA makes an adapter for jeep T5s to an NP205, but I will have to dig through my catalogs.
