Update so far,
As NorCam noted "in 1969 the lock should accept an "E" key section...so maybe you can try to see if another E sectioned key fits into the keyway. I assume it's maybe a "J" section for a 1970 ignition or maybe an "A" section for 1971"
I had all three "E", "J" and "A" keys in stock in a small bag at home. The only key that slides in easy and all the way is the "E" stamped one. (See Photos) I also took the column switch off to see if it had an ink stamp on the back and it did not but it has a metal stamp of "4K36" which I am not sure what that means ?
I currently have paint thinner on the tape hoping it strips off to show a stamped date code there. Later on tonight I'll post a photo of my finding under there.
