Why not just buy new spiders, or better yet, replace them with a drop in locker like a lockrite, quicklock, etc? If you are set on getting a different differential, up through early 77 should be a direct bolt in with no modifications. Also, 76-77 are disc, which can be a benefit, but then you have to change your braking system to accomodate it.

The diff from any Dana 44 will fit. It is the ring and pinion gears that will be different as I believe that your 73 is a low pinion, standard rotation, where the later F-150s (and I also believe the late 77-79 F-250s) Dana 44's are a high pinion, reverse rotation housing. So pick a diff and have at it, just make sure the axle shaft spline count is the same on the new diff. But then again, as Ted said, if it just ate the spiders, why not just buy new spiders and save the setup issue as you may have to shim the new diff, unless you want to switch out to a locker or some other traction control device.

I was pulling something to hard a couple years back and mine ate the spider gears also. I've heard that is one weak point of that front axle. I chose to pay a bit more, I think $200, and upgrade to a truetrac limited slip. The other weak point is the u-joints in the axle shafts. Replace them while youre in there.

Mine is not any harder to turn. Do you have power steering? Is yours full time four wheel drive? If it is, definately do not get a locker. Also, terminalogy can be confusing--limited slip and posi is the same thing. Posi-traction is a chevy term for limited slip. Don't get a locker unless you are a serious off roader. Good luck, maybe find one someone is parting, I see two on craigslist in my state being parted out. That is cheaper, but used parts can be worn out parts.
