The extra descriptive plate with the axle/transmission/colour codes was not used until 1976. If your FJ40/55 was sold in North America, there's a 99-44/100% chance that youre truck's got 4.11 gears and an H42 or J30 transmission anyways. From 1955-1964, the year of the truck was stamped on the frame in front of the VIN. So a 1964 FJ40's vin would start 4FJ40.
The ID plate usually contains the following information:
Vehicle Model/Production Code
Body COlour/TRim Codes
Plant Code and GVW
