Gas tank date codes

[crobjones2]

I was planing to buy a new tank, but if I can find a date code I will try to save it of course. I have a big dent on it, around three inches in diameter and one inch deep.
What's the best way to fix that dent? A little fuel in it and a match, or?

Gus- try a radiator shop. The tank is soldered together. I was able to get my filler neck re-soldered by an old school radiator guy.

My 1969 Z28 Camaro Vin # 124379L502278; build date of 09D 1968 has a gas tank date code of 5  69.

Thanks,
Mike

03D
68 36

[FortLangleyBC]

My 1968 05C is 68 42
Myself 1969 04C is 37 69

Both are consistent with the previous data.

my 69 Camaro is a 10C car....

Awesome database - thanks Kurt😀

My 67 05A

17 D 7   (The D is backwards)

[KurtS]

Here's the latest compilation. Trends are obvious.
67 has a calendar week code. 16 D 7 would be the 16th week of 67, day shift. 40 6N would be 40th week of 66, night shift.
The format changed in 68 and 69 to have the week counted from the beginning of the *model* year. The extended 69 model year used tanks dated for the 70 model year.
LOS and NOR data is intermixed and shows the same pattern.

My 12D built 69 Z has a gas tank code of 19  69

[BULLITT65]

Looks like that lines up Larry..

[X33RS]

I knew it was original but I can't make much sense from the date code.  Like most others I've seen it's an odd series of numbers for a 68 built car.  Even using a Julian format it doesn't make sense, and Jan 9th, 1969 doesn't make sense either.

But yeah like you said, it lines up with the other weird numbers for late 68 cars.  Just thought I'd post because I don't see a 12D car on the list.

[69Z28-RS]

X33..  The gas tanks are apparently dated by the *week*, beginning with initial production for a *model year*... so your '69' means 1969 model year, and the 19 indicates the 19th week of production for the 69 model year...
My late '69 (09C) is dated 05 70  - assumed to be correct since in a normal year, a September car WOULD be for the next model year (1970 in this case)...

Not sure if you are looking for more numbers, but mine is:
10A car with 05 69 date coded tank
