With all due respect, then itís possible that a 06A car could have a 027-9 valve?
Possible?? Yes. Very unlikely.

Looks like we may have stumbled onto something out of the ordinary in terms of conventional date coding / car build on this particular part.
The dating is typical and predictable.
I have 120+ datapoints. Looks like the incoming batches were large (small part, easy to store), so the usage stretched over longer time periods.

My LA car is 04A, NCRS production date is April 3, 1969 and proportioning valve is dated 052-9. Thatís Feb 21.

My VN Car, 04B (also Cortez Silver) has the exact same date code for the proportioning valve - 052-9.
