Can anyone help me decode my serial number? I have 1966 Jeep Cj5 3 Speed V6. All websites I have looked into don't give me an engine code for the 7th digit and say there should be a total of 13 digits. This is a picture of my Serial Number badge on the driver side of my engine compartment. When I bought it the guy told me it was a 66' but the title said 67' just trying to get more info on it, Thanks!
