For your reference folks.
These are only the frame numbers that are imprinted when the frame is manufactured at the Honsha plant (manufacturer of the frame assemblies) which were then shipped cross town to the Arakawa Yoshiwara Plant for final assembly.
The top boxes are dates so "8001" would be January 1980 production totals for the entire month.
The dates and frame numbers do no necessarily correspond to when the truck was fully assembled and delivered to port for shipment to the US as well as the model month it would correspond to for sale once in the US.
Anyway, hope this helps folks who are into the more historical aspects of Land Cruiser manufacture.
