Good Year Diamond tread 700/16 or 750/16 tires

I’m building a period correct car and for it I need 2 or more GOOD YEAR 700/16 or 750/16 even 800/ 16 in. DIAMOND TREAD TIRES. Don’t have to be perfect but must be in usable condition.
Vintage tire dealers sell Good Year 650/16 Diamond tread but it is too small. If you know of someone or a tire retailer which might have the tires I'm looking for please let me know. Thanks.

I would think that Coker would have what you're looking for.

Thanks NTFDAY,
I tried Coker time ago, but they don't have it, if a recall right they don't sell Good Year, they do sell Firestone. I've tried Kelsey tires, Diamond back between others. Good Year doesn't manufacture those anymore according Customer Service. I hope I’ll get a reply of somebody that have those in their shop or barn without use and willing to sell them or know of a tire retailer out west or someplace else that still has old tires in stock at the back on a shelf.
