The ones shown in your car are not the original Ford type that was available. They are either original aftermarket, or reproduction aftermarket ones.
However, don't fear ; reproductions of the originals are available as shown in the attached catalog cut from NPD's catalog, as well as from other suppliers.
Also attached are 2 pages from the 1968 Ford Accessory Catalog showing the mats (the previous years were the same mats, the 1968 catalog just has a better picture of them).
