When I bought my YJ, the old man (sorry guys) handed me a Chiltons book and said, "Here, I'm not gonna need it". I got home and thumbed through it and it had all the reciepts from work done, parts reciepts, and even a little schedule in it everytime he had done oil changes/lubes/EVERYTHING. Now that was a good find. Made me feel alot more secure about my decision. How far back can the build sheets be found?
