> This has to be extremely rare. Was this primarily out of the US that the > single headlight was used then? In 57, there were some states that did not allow multiple headlights i.e. 4 of them, so the factories started out the year with single headlight models. A few, such as Imperial, Chrysler, DeSoto, and Mercury, built mid year options with 4 head lights instead of two. There were some after market 4 headlight units for 57 Fords. Therre were some faux 4 headlight systems, Lincoln, Plymouth and Dodge, in 57. In 58, I think the only American cars without 4 headlights were Studebaker and Packard.
