Dana 44 Front axle no oil?

[outfield]

Look for a 1971 to 1976 big hub Dana 44. These all use the same locking hubs as yours, and it is a direct bolt in. The only changes will be what I noted, brake master cylinder, proportioning value and brake lines.
If you watch for a while you can find good deals on these. The first thing you need to do is figure out your gear ratio. If you find one with the same ratio, your way ahead money wise. Pull the cover and do an inspection if it has been sitting, walk away if you see any rust.
Good luck.
