A modern, good, cheap radial is the Uniroyal Tiger Paw AWP II.
Nice whitewall, I have them on one of my cars.
US Royal and Dominion Royal both became Uniroyal in 1966.
Since it's a name that existed when your car was built, it's a reasonable replacement.
I mean at least it's in the ballpark unlike some Korean tire.
The Coker option is fine for a car that gets pushed on and off a trailer, but bias ply tires are lousy to drive on.
Real money for those Coker tires too.
I don't know how I didn't die back in the day ripping around on bias ply tires with drum brake big block cars.
If you're okay with Motorcraft parts on your car, then I'd say the Uniroyal's are a good choice, but if you want all Autolite, then Coker bias ply it is I guess.
