The Check digit is used to calculate the characters in the serial number and gives it a single digit code that can be used to verify the serial number is legitimate. (Note: The Check digit number varies depending on each specific VIN number.)
For all 1986 Corvettes, the Vehicle Identification Number was stamped on a plate on the inner vertical surface of the left windshield pillar visible through the windshield.
