Date codes for the 1970 model year - complete list?

Hey guys,
I am working on another article for HH. I have access to a very original car that was built a bit early, in the month prior to the scheduled production date on its fender tag. Looking at the date codes on it so far has been fun & I have started a spreadsheet to track them.

Not all of the possibilities listed below have been checked on this car yet, but I have seen them on other 1970 model year cars. If you know of something not shown, please mention it so I can add it to the list and / or check it on this car.

I will edit the list as more possibilities are reported.

Thanks!

Barry

you missed Scott's "tires"
& my "horn switch" (added while you worked?)

Dimmer switch.

Upholstery ink stamp (backside of seat covers)

Convertible boot cover date and manufacture stamp.

Early cars have different.

Not date codes but related. Early car, see if the body panels have vendor codes or all zeros.

OK, updated again.

I may have called something by a different name, as an example "upholstery' was on the list as "Seat upholstery".

Thanks guys!

Hi Guys, Have a question. Have a 71 Satellite Pilot Car with a bunch of 000000 on front fenders. What do they mean if anything and can they be found on cars built later in the year? Thanks Terry

The sheet metal on pilot cars were often all zeros, likely because they had not been 100% accepted as production ready, and or, were not yet assigned a number by the metal stamping vendor or Chrysler. As far as I know there is no "decode" available for these numbers once chosen, just something for Chrysler and the vendor to use to I.D. or track them (I'm guessing here).

Not 100% sure, but I believe that the diodes in the alternator were also date coded.
