Cummins swap questions

I have a spotless 69 F100 body on a 79 F350 4x4 frame . I just bought a 91 Dodge D350 4x4 , cummins , 5spd. (rusted to pieces )
Im going to swap the cummins into the Ford of course but I have a few questions.
Will the NP205 from the 79 F350 bolt on the back of the getrag 5spd from the dodge ?
Both trucks are Dana 60 front axles . Would it be easier to put the right side pinion dana from the dodge (which I dont really want to) in the front or swap the t-case from the ford to the 5spd ?
Thanks for any help !

Your case won't bolt on, it's a 31 spline and the Dodge uses a 32 spline. You may be able to use a case from a 94 and up Dodge, which would have the left side drop.

The Getrag is a POJ tranny so it is better to find a 4500. Keep your Ford D60 as it is better than the Dodge D60.

Advanced adapters should be able to set you up with a adapter from the getrag to the NP205. In my opinion it would be a mistake to swap out the 79' ford front axle for the and transfer case for and alternative. Just get a adapter and a longer front drive shaft.

The 79' Ford front axle is a high pinion with king pins and is very desirable. The dodge front axle is not so hot. Plus the NP205 in my opinion is preferred over a newer style transfer cases.

Just because advanced adapters doesn't list it on their website doesn't mean they cant set you up.
