Decoding Jeep CJ VIN Numbers 1971-1986

82 CJ-51975 to 1986 Jeep CJ VIN numbers are usually located in several possible locations. You should find a tin plate on the drivers side firewall near the brake master cylinder. You may also find one on the drivers side dash or the inside body panel by the floor near the parking brake lever. On mid 80’s models it should also appear on the windshield wiper motor cover inside the Jeep. An abbreviated version is usually found on the top of the passenger side frame rail above the rear wheel.
