Thank you Captainfab for the link! I called my locksmith and got the lock re-keyed right away. But as I was installing it, I discovered the latch on the right side wasn't moving, so foolishly, I decided to remove it. Apparently that latch had not been touched in about 57 years. Had to drill out the screws and then retap the threads. Haven't done that in a while. Then, after lubing it up and thinking everything was working, I closed the tailgate - which is now stuck. It appears I will have to adjust the striker plates! Anyway, good progress!
