My 02A Norwood car has a tank date code 25 69 with the 5 upside down also,like one other member.I just had a chance to look for it today.
Is it the 25 day of 1969?

[BULLITT65]

no, more like 25th week of the model year.

Here's my stamp, 02D car. Also a pic of the drain that must've been there when I bought it back in '77. Sorry the pic is so small, the stamp is "28  69"

My 03B Norwood

My 69Z has a build date of 10D (4th week of October 1968). I looked at the gas tank code and found
"69 01". Not sure what that means. Does it mean First week of 1969. I think the tank is original but not sure. I'm the second owner.

that is probably 10 69, read backwards or upside down

[asm69]

how ever its read. Does the gas tank stamps mean that the gas tank is original or replaced?

The point of this section, "Research Topics and Reports", is to get data from known original untampered with cars to determine if a pattern exists to understanding date codes and/or other information. If you go back a page, you will see a spread sheet where your tank date fits the collected data and can, therefore, be assumed as original to the car. New model cars generally would be introduced in September. Gearing up for production required parts made ahead of time. Your date, 10 69, or 10th week of production of model year is consistent with data. Production of gas tanks probably started in early or mid August (68) to meet demands of new model production. So say 1st week of August, count up 10 weeks, and that is when your tank was made or about a week before your car was made.

Thank you. I looked at the spread sheet. Good to know gas tank is original to vehicle.

My 11D 68 ss/350's tank says 68 19

[x66 714]

My 02E LA car has 68 30 code.
Pulled the one from my 69 to have repairs & the tank has 29 69 which can't be right for an 08E Norwood. I would need a 2 70 at least. Wonder if they made a 3 70?
Time to find another tank for the 69....Joe
