Looking for picture of original flat top header gaskets

I am looking for a picture or diagram of the Tri Y original header gaskets used at Shelby around March of 66.

I am trying to find a pair of these or good substitute.

Going to be hard to find original. These are a good replacement

They come gray so get can of VHT flameproof flat white header paint. It will take about 4 coats to cover but 1 can will do it

Still looking for a picture of these.
