The first one I got was at the dealer. Gave them my last 8 # of the vin and they printed it off. Took one minute. Someone elce there must know. Then I went on the Mopar web site ( I thik Jeep.com)under the owners section and there is a place where you can e-mail D/C and ask a question. Ask for a build sheet. You will need to give them your vin and some other info. I got a build sheet by return e-mail in about 2 or maby 3 days max if I remember correctly.
Someone at the dealer should know how to do it. My dealer gets one before they do work on a jeep to verify original equipment/options etc when they have to work on it. That's what they told me anyway.
