I know perfectly well that the serial number will be the year of construction, but I make an example:
If a Toyota 4FB15 with serial number 15000 is from the year 1986, Toyota 4FBL15 with serial number 15000 is 1989.
The Toyota forklifts with letter "L" are considered different at the level of the frame.
For this reason I would be interested to have a table with years of construction of the Toyota with the letter "L", as in my EPC these models can not be entered.

Not familiar with the "L"- models in the US have a "U" in the model designation. Maybe the L has some sort of destination designation. The serial # will give you the year
