I would go with Bairs or even Ikerds. As far as shipping, it is easy get a 5 gallon bucket from Home Depot and drop the diff down in it. It will fit tight but you will need to remove the cover and axles and drain the oil out of it. It is a Hazmat so UPS will not take it with the oil in it. You can put the lid on it and tape it all up and then it also has a nice handle on it. The bucket will keep it from getting damaged and you will not make an enemy out of your UPS man by building a wood crate for it.
I have cheap ice chests I use for motorcycle engines and stuff like this. They come back in them and save them for the next time. No tear down except for the rear cover.
I shipped mine to Gary from Missouri in a plastic cooler bought from walmart and stuffed with semi-rigid foam and the axles removed and wrapped in bubble wrap. I then duct taped the cooler lid closed real good and shipped it using Shippo to print my own labels. I even printed the return label and put it in the cooler so he could ship it back. Shippo was way cheaper than going direct through the shipper. I had no issues whatsoever and Gary did a fanstastic job as always. I also had him swap out the wimpy 2.87 gear for 3.73's. 2 years now behind my LS equipped '81 and zero problems. Worth every penny. Good luck!
The cooler would work, didn't think about that one, just had customers use 5 gallon buckets. You can also save a ton on UPS if you go online and make an account with them and do all of it online. Then you just drop it off at the UPS store vs. having the UPS store ship it for you. Would be shocked on how much you save. We have also gotten really nice wood crates that would come in and even thought about building some to ship the diffs in that gave a good crate to send the core back in. I asked our UPS guy about it and the stare he gave me answered the my question.

So you have a 81, did you build a DANA for it or did you convert it to a cast iron diff?

converted to an iron diff. Although my Dana was working, when I opened it up it was on its way to failure. For the cost involved it just made sense. Pretty easy swap. Hardest part is just getting all the pieces. I was lucky enough to find a complete rear end out of a ‘79 local for cheap. Unfortunately that one had an all to common cracked carrier. Gary hooked me up with a new Eaton unit and was able to reuse the existing 3.73s that were in it.
I had mine done by vtech along with trailing arms, they did a great job. I had mine rebuilt and re-geared rather than a swap out, and new used good oem shafts installed. They will send you shipping boxes, only took a few weeks.

How long ago did you have the work done? How many miles since? Was this a cardboard shipping box?

They use heavy cardboard boxes, I’ve put about 6k miles on it in 3 years, mid 400’s HP and more than a couple burnouts (ok way way more). It’s no trailer queen.

Were you able to modify the D44 cover and bolt to the iron diff or did you change the mounts over? I had just started to look into offering a conversion but we started upgrading the D44 instead and going to work on a kit for the Eaton if the D44 didn't work out.
Gary did the rear end, trailing arms and steering gear on the 68. 10 + years later they're all doing just as good as the day I got them back.
If you choose him to do your differential, you won't regret it.
I live close enough to Gary to visit his shop a few times, witness his work on differentials and steering boxes. Top shelf work, great attention to detail. None better. He’s also a superb communicator, I learned quite a lot.
He’s currently very heavily booked. A tribute to his expertise and communication.
