the chain link's inner dia.
Did they use one of these:

Or something like that?
Can't see how they would get the last link over the shackle ends
I'm not a fan of these link repair links, unless way over sized. Even then, I'd
think it over several times before using them. Note the ever present 'working load'
rating for anything to do with chains. Know the difference between china terminology
'proof', 'breaking', 'working', etc. They are legally defined terms with real
documentation on what they mean/represent/etc.
Your idea of a stack of washers will center and as John said, don't spread the
shackle at all....there are many other ways/methods to fasten a chain end to a
plate like this and shackles are NOT one I'd have chosen
that used a shackle to a plate steel tab for a lifting beam I made
See how the chain has the shackle pin through it.

another way is to sandwich the end link with plate steel then have a bolt through
a hole in the plate and chain end. The tensile strength of the plate steel must
exceed the chain working load rating.
This is a nit, as I'm anal about this kind of stuff (from experience with cranes,
big cranes)
I don't allow any China shackles on any crane lifts I approve. I wouldn't use the on my car either. I've broken a couple WD hitches already....

Look closely at the picture and you'll see a flat spot on one side of the shackle. On both sides of that end of the shackle they've shaved (no grinding grooves) a slight bit off the sides of the end. This flat spot enables that end of the shackle to slip through the end chain link.Am curious on the last link to the shackle, as the shackle dia is way larger than the chain link's inner dia. . .
Well, this is quite a discussion. I guess the only votes on my question points to analaity. I currently have no accurate weights on the trailer. I will see what I can do about that. There is a CAT scale a few miles down the road I have wanted to visit. I guess now is the right time.
Unfortunately the trailer is currently parked on a slight slope. The good thing is that I have acquired and installed an after market receiver and ball/ball mount (rated at 1,500 tongue, 15,000 tow) that have a rated capacity that exceed the potential weights (9,590 GVWR * 12% tongue weight = 1,150). That means I can get the trailer out of the yard and to a flat level parking lot to install and adjust the new hitch.
Youbetcha I'll be getting the most accurate before and after weights and measurements I am capable of.

What other ways/methods would you recommend? Why wouldn't you use shackles?

First, repeat that I'm really an optimist and really think the Andersen
design is VERY elegant in architecture...but...as with all things...the
devil is in the details.
BUT...am trained in design and to look at things critically, as all
things designed is not for the good days but for the worst day out
there where the gorilla and idiot will break it or Mr Murphy crosses
your path
CDRs were a thing of life as a designer and then as management. CDR
as in Critical Design Review where EVERYONE tosses rocks at the design
till either they bounced off or what broke acceptable to management
Shackles have their place, but for me, I'd attach the chain differently
as stated in both of my previous posts
To me, shackles are for a joint that will be disconnected often enough
to warrant that. In this case, I'd have it bolted in a sandwich of
plates and/or tubes welded onto those plates.

flat spot on one side of the shackle is NOT a good thing
unless they calculated that the now reduced cross section of what I
think is the weakest portion of any shackle is still strong enough
for the calculated dynamic loads...plus some margin
To me, indicative of the designers and management philosophy and
fastidiousness for the big picture and details in the rat holes
What some see or consider analaity, is, IMO, fastidiousness of details
Where I've used shackles and the chain can not slip over the ends, I
have flipped it to have the pin be the chain side and the hole or
whatever on the other end large enough for the shackle end to pass through
