It will fit a Dana 44. Keep in mind there is two different spindle lengths. Thinking the 44s is just a tad shorter than the 10 bolts. As long as you have the spindle from the 10 bolt you will be all set. As far as the axles go the stub shaft is the same for a 10 bolt or a 44. The difference in length of the spindle isn't enough affect them. If you use the longer spindle with the hub from the shorter one you won't be able to get the wheel bearings tight enough. The opposite way you can't start the hub lock nuts. As far as other axles. I sold a complete set of spindles, 8 lug hubs, rotors, backing plates, calipers etc. from a 10 bolt. He installed it all on a Dana 44 that he said came out of a late 70's F150, and he had it under his CJ7. He had put a Dana 70 under the back and wanted to upgrade the front to 8 lug as well.
