You are correct. Bright side is that the dodge D60's are cheap to buy. You can link them without too much problem, and I think the unit bearing will hold up good enough on something as light as a dakota, but you have the disconnect to deal with. You can either replace it with a one piece shaft, but then you have no locking hubs, or you can get a posi-lock to manually connect/disconnect when you want. I have considered this axle just because of the price and easy to find, just have not made up my mind yet.
D44 from Bronco is a decent axle. It does have the bigger u-joints for a D44, and parts easily available. You can make them survive as long as you don't thrash on it too hard. I ran a bone stock D44 with 38" swampers, 5 spd and a 4.0 6 cyl for two years and never broke anything, but I am a conservative wheeler. I have a buddy that ran 35's on a D44 with alloy shafts, CTM's and drive flanges, and he broke something everytime we went wheeling just because of his heavy right foot and 300+ horsepower.
You can buy a stock D60 cheaper than you can build a D44 putting alloys and CTM's. Just depends on what your long term goal is. I would say the week point in the D44 after doing alloy shafts and joints is still the hubs (factory Ford hubs are stronger than aftermarket). No way around that without going D60
