Am curious on the last link to the shackle, as the shackle dia is way larger than
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
