Do you still have the vehicle that you put the motor from the Durango in? If it's another Durango or a Dakota, I'd keep all that stuff. I don't know if it would be worth the trouble to swap the 6 lug axles out to put it in something else. I have an 88 D100 that I am removing the 9 1/4 out of, and replacing it with an 8 3/4 from a 70 D100. The 9 1/4 has Bonneville Salt Flat gears (2.45) and the 8 3/4 has 3.55 gears. I'm a semi hoarder of parts too, so I will put the 9 1/4 in the storage shed and let somebody haul it off for scrap when I kick over! LOL
