One issue with a VIN on an older vehicle is that it does not conform with the standard 17 digit VIN.
Many states will add aditional numbers in front of the actual Toyota VIN to allow it to be entered in the computer data base. Or some will add zero's behind the VIN.
Usually it is just zero's added in front of the VIN to get the 17 digit requirement.
Sometimes it is a combination of letters and numbers to get to that magical.number of 17.
If you try internet searches, I would suggest starting off with just zeros in frontnofnthe actual VIN. Then try Zeros after.
