Mopar locks back then all had the key code stamped on the locks. Sometimes it's hard to find but look for an ES or EP followed by 4 digits. EP was the primary key for the the ignition and doors and ES was the secondary key for trunks and glove boxes. Once you know the key code, you can know the pins inside the locks and which locks are worth disassembling. The 5 pins have 6 possible depths. There were 3000 possible key codes. An example EP2912 translates to 22164. I made an Excel spreadsheet for all the possible codes. I used to have all the possible pins, springs, etc but sold it all about a year ago. I don't remember who the member was. The spread sheet is on my google drive:
