For what its worth, I have a 66 Galaxie 500, and it has the lights under the dash (one in each footwell). They look exactly the same, so if you're looking for some... Probably used in other years of cars too.
My 69 has the ranch hand side tire holder, PO had it chromed. Also has dash mounted hand throttle and chrome drip rail moulding. Doubt that any was factory option on this truck, PO cherry picked parts for 20 years to build it, kept all the cool stuff he found over the years. He also chromed factory air cleaner and swing away spare tire carrier (he had a buddy who owned a chrome shop). Lots of chrome bolts and pieces. He had the headlight rings chromed, the hold down for the windshield to the hood, fan pulley, etc... Not to much, tasteful IMO.
