Chassis code and build dates, decoding VIN and Chassis codes for dates of build- my number appears later than known delivery Options

[DRPHIL914]

i was recently researching the chassis number decoding and there is another older thread about this. Based on that information , my chassis number of 472-9075
states that my chassis was built in the 47th week and 2nd day do the 1975 model year.

BUT weren’t some 75’s built in late 1974? so what is the first month of the model year build is it January 1975 or is it October of 1974?

my car birthday according to my COA is Sept 15, 1975. it was special ordered L99k color with full appearance group. it was offered and money deposited in the summer of 1975 and it was delivered and paid , picked up on October 15, 1975.
so how can the chassis build date be 47th week? that would put it in November 14 or so of 1975 if you go tomorrow January 1 for the calendar year.

Is there a door jamb sticker with the vin and production date? —assuming not

so when i bought the car the original door jam sticker was still affixed, there had been a body respray but they didnt do the door jam area. BUT when i had that stripped off and the car was repainted, with out telling me, the body and paint guy pulled that sticker out. I had it, and i had a new replacement one made by Carbone in Poland, and the date on that original one, and what was put on the new tag was/is 09/75

Well the sticker agreeing with the COA, I think is pretty compelling evidence that September of 75 was the production date.

I was confused originally posting, thinking L99K was a custom color confusing it with L98 or L99 (no suffix).

Could be it sat that long as a copper metallic chassis. That is a long time though.
