Phaeton hood/top saddle

[FordyForever]

Perhaps someone can help with a question about a missing top saddle for my 1929 Canadian built Phaeton. The offside saddle is missing and there is just the stud sticking out (slightly bent). Replacement saddles are a different design and require a narrower stud. I'm guessing the existing saddle is from a completely different car.
Hopefully I've attached a photo of the nearside saddle. Does anyone recognise it, so that I might be able to buy a pair for it? Thank you so much!
