Actually it is a 1958 or 1959, it has the single headlight, factory grill, spare tire on side. This is actually a VERY rare truck because most of them have been scraped. It was built by the factory as a fleet economy truck for commercial / business truck. I seen one before selling upwards of $25,000.00 (about 4 yrs ago) but it was a complete numbered resto. It came from factory with no chrome, no dual headlights, no emblems, etc.
Here is one I ran across last night & it also has some good info with it.
