I think they are worth cleaning up.
Remove the rust with a chemical or blaster.
Lightly smooth with emery cloth.
Insure the seal area is smooth, as the bearings run gear oil. I think this is the area you need to worry about the most.
Test fit the bearings. They should be a slip fit. If they are slightly sloppy, you can peen the race area.
Don't forget to run a chaser on the threads.

 

I think I would try sand blasting then polish with a super fine sand paper like 1000 or 1500 grit so it’s seals will still work

Yeah I may as well try before condemning them right. Be a good use to try out my "pipe polisher" too.

First off, do you have shafts, hubs and brakes also with the axle? if you are missing the big components, then I would look for a different donor axle. Dana 60 rears are easy to come by and I wouldn't waste the time and money on an odd ball axle.

 

Yes I do. It's complete. The hubs have new bearings and are attached to brand new rotors for a disc swap, the shafts are in storage, although course spline so probably won't even use them... parts for a disc swap were ordered years ago when it was pulled but subsequent moves and life in general caused it to be pushed away and forgot about. At least the parts stayed in storage.

I like this axle since it's not a full width. That's the point of keeping it. IIRC it's like 68". All my front HP60s are bare center sections so one will be made to match.

Then yeah go for it and try to clean them up. What size is the spindle bore? Are the full float hubs/axle shafts the standard 8 on 3.96" pattern? Not sure if IH used the same add 6 on x.xx" pattern that Jeep used on some of their full float rear axle shafts that makes it nearly impossible to get different axle shafts with a better build and higher spline count.

 

Not sure on the bore but the bolt pattern is 8 and looks to be a 4" spread with a tape and the eyecrometer

Update... pulled the carrier and pinion. Bearings show overheating signs...

And this is what a 36 hr soak in evaporust did!

A 3.5 gal bucket of that poured into a 5 gal bucket is a perfect setup to soak FF ends in.

Big improvement! Polish the bearing and seal seats up with fine wet or dry or emery cloth and you should be good to go.
