Adam,

If Amel doesn't have them fellow SM owner Paul Stascavage from Rita Kathryn had the same issue and had some replacements machined.  He had some extras made and as of July 2020 still had some available.  See this post:  https://amelyachtowners.groups.io/g/main/message/53463

You can ask him If he still has some for sale by replying privately in that thread.
