I have one of these divorced dodge cases and just asked a question about it actually. I've done some research lately and here's what I've gathered so far.
NP200 (Dodge Divorced) has a parking drum brake on the rear output. very distinct.
NP205 (Dodge, 60's style.) is much larger than the "regular" 205. heavier as well. comes with the 1410 yokes. this is the one I have.
NP205 (Dodge 70's style) resembles the newer 205 -- being smaller and a bit lighter, but still heavy!. 1350 yokes.
correct me if i'm wrong, but i feel pretty informed on this!
