Parts identification help

[starliner62]

I have a pair of sun visors I found while digging through my parts stash. They are labeled NOS but have no part number.
They are not padded, light gray in color and are complete.
I compared them to a pair in a Champ truck and they match up pretty well except they are about an inch shorter.
I'm guessing maybe a C cab. I checked a few cars and they have three screw that hold them on. These visors only have two holes.
Any help is appreciated.

Looks like my '61 Hawk! The mounting bracket is the same except the Hawk's is chrome.-Jim

Think they went from 3 hole to 2 hole around 1960 , not truck

These are '61 or later with the Center mount Ball Studs, the Length will tell of they are Lark or Hawk.

No Trucks used the Center Mount Clips and Ball Studs.
