Gary, we have a local locksmith who's Father was a locksmith and he is also a car nut like us. He knows the codes and even has the tool which is used to cut/notch each key per the code or what he finds on the lock. Kind of reminds you of an old label maker but he keys in a number, punches the key, keys in another number, punches the key until he has the code punched in. He also stamps the code if one wishes on the key blanks which I had done for our 68Z restoration. If you cannot find anyone locally send it to me and I will ask him to fix you up.....
