I know nothing of the conversion, but your downgrading to go with D44's. Your rear axle should be fine with that engine, and your front will be fine if you do only moderate wheeling. But with the weight of that engine I would put a D60 in the front. I doubt anyone makes an adapter for that engine, however you could probably use a zf 5 spd, but then you'll have difficulty finding a xfer that is passenger drop. So if you do it, get centered rear and drivers front axles, and you could use a ford xfer. That will be one fun swap,lol. So get lots of the cold stuff.
