Yes, I'm new to forums. I'm purchasing a 1983 CJ8 but am wondering about validity of Vin number and how to decode numbers. The Vin is 1JCCL88E5DT001795. I also have info from seller of numbers J172376 88 and 06 3B 1BA on firewall. I found one site on web that when Vin entered replied invalid number. Jeep is in Texas and I'm in New Mexico trying to do purchase. Am raising 4 grand kids and thought this would be a fun project for us. Thanks for any help you can give.
