Irwin 37 ketch mast head replacement

[yem23]

Below are pics of the top of my main masthead. There is a triangular shaped plate, mounted on a hinge for a masthead light. During transport of the boat, that SS plate was lost. Any advice on replacing it? Anyone with an Irwin with a similar configuration? Pics of your current configuration? It looks to be a custom fabricated piece....

Do you have any idea what the lost piece looked like? It's hard to give advice from here, but at first pass, it seems the most direct thing to do would be to re-make the lost part if you have an idea of what it was.
