Center console date ?

      Noticed this 46-11-9….hidden under the ashtray door slide. Thinking it may refer to a date of November 9, 1971?  Or would it be September 9,1971
Trying to hammer down date of production of my hs30-10324 car if it is possible to get down to a month, or day of production.

'46' indicates Showa 46, which is 1971.

Japanese calendar dates tend to follow USA format, which is Year-Month-Day, so '46-11-9' is November 9th 1971.

This of course indicates manufacturing date and/or quality control check of the console, not of the car. It may even be for the FRP moulding of the console body and not the completed article.

Consoles were made in another facility and then shipped in batches to Nissan Shatai's Hiratsuka plant for the build-up of the cars. The batches may well have been made up of consoles made over several days or even weeks, and it is doubtful that they were attached to cars in sequence according to the quality control date - although it is logical that they would normally have been attached to a car within a few weeks of production.

I think it is fair to say that most quality control/production date stamps on the components of these cars tend to average out at within a month of the car being given its 'OK' completion check, although it is possible to observe the odd exception which tends to prove the rule...
