There's another oddity which can 'pinpoint' (intended) an OEM radiator, which I remember someone mentioning before but I couldn't find the thread.

Notice the OEM radiator has this white "pin" on about the 10th row from the bottom.

In the prior discussions (which I can't find), folks surmised this is some sort of 'date code' to the manufacturer.

What do you think its purpose is?
