Not sure what month mine is but it was built in Oakland 1212 units in.
The sequence resets each month. I'm guessing you know that the last 2 digits of the first half of the serial number indicate the month made. Are they illegible?
The only clutch screws I've found are ones holding the data plate on so far.
On my 1941 made in October, the only places that had clutch head screws were the data plate, the front sections of hood lace, and a tubing clamp on the chassis.
