The date code for a distributor would read "number-letter-number(s)' where the first number would be the calendar year of manufacture, the letter would be the month of that year (A=January, B=February, and so forth (I is skipped because it looks like a one) to M=December), and the last number(s) would be the day of that month (1 thru 31). I'm sort of guessing here, but a '67 model year car could very well have a distributor with a date code of 6G-- through 7G--. It's possible a '67 model year car might have a distributor date code of 6F-- but I'm pretty sure you wouldn't find anything earlier than that for a '67 model year car.
I'm seeing 4 different distributors for the '67 model year 4-4-2, depending upon application, as follows: 1111042 (all 4-4-2 including early W-30, except with UHV ignition, 1111151 (all late W-30 except with UHV), 1111188 (UHV early including W-30), and 1111179 (UHV late including W-30).
Date code applications are pretty much an educated guess but I'm estimating what I said above is fairly close.

Or, buy a cheap 5/16 1/4 socket, a cheap 1/4 long extension and use that to turn the oil pump driveshaft. Olds don’t require the distributor to be in place for proper oiling. Just make sure to either weld the socket to the extension, or tape it in place. Anything to ensure the socket doesn’t fall into the engine.
