|Note the "4F" date stamping on this Mustang rear tag light assembly. This is from our 64 1/2 HiPo Mustang Coupe with a scheduled build date of June 8, 1964. The original license plate light on this car is dated June of 1964.|
Here is another one of my "geeky" details for 1965 and 1966 Mustangs. Even the rear license plate light assemblies on these Mustangs are date stamped. I will note that I have observed many NOS Ford service part rear license plate light assemblies that did not have a date stamping.
Our example here is dated "4F" for June of 1964.
