Gas tank date codes

[tmodel66]

I was looking thru the data and saw no 07A '69.   So here is one.  07A  48   69

Hi. I'm the "new kid on the small block" with an early 69 rs/ss vert. Build date 09B. my tank also shows 1 69. If you would load me up here is my info: TRIM TAG 69 12467N106966 TRIM712  72B  09B  VIN# 124679N508233  partial hidden vin cowl 9N508233 fender run # 33 By the way my passenger window glass is tinted date coded and has the"astro vent". I'm going full frame off and as I do so I will be picking up all codes and keeping records. You guys are aces and this forum is superb. Thanks ! ED

Ed,
Thanks. The one thing that stands out is the Astro Vent glass. Are you sure that's not a sticker? What's the date?

Here's another 67.

LOS 05C 16 D 7

[MyRed67]

  My 11A - 66 LOS built coupe has 40 6N  right on the bottom of the Drivers corner.  This 40 would be correct for actual Calendar week, but not with the theory that Aug. 1 st. being week 1.  And wonder why the N is at the end.   I'm attaching a pic.

[KurtS]

Thanks guys! So it looks like 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.

Nice job, Kurt the Code Cracker!

I checked mine last night.   I've an original 09C Z28....   
The gas tank code is  5  70 .    I was thinking it must have been repllaced before I purchased it in 1976, if it wasn't made until 1970??    but I notice several other 08 and 09 cars with 70 dates. 

So how does this code work for the extended-run late '69 cars??

It still uses the '68-'69 format, but begins 1 70 when the '69 model year should have ended but was extended because the '70 Camaro was not ready for release.
Your gas tank was built in the fifth week of the 1970 model year and IMO is original to your car.

Hello all,

 I'm new here and just a lurker learning after having my car sit for almost 25 years garaged and decided to get back into this. I checked on my (what you now call a survivor car) 67 SS/RS 396 LOS car I bought in 1980 from the original owner and see a 4N7 on the gas tank. The body tag is 04B. I see the tank was sprayed black and I thought the owner did that but I read somewhere recently that LOS Camaros had black tanks.

Regards,
Mike

   My tank is the first 67 on the list(40 6D) with the pic. above  11A build LOS coupe, there was no paint on my tank.

[KurtS]

Mike, I've seen other LOS tanks with blackout on them. I think there's a pic showing the plant painting the tank.

I do see what appears to be black on the left side of your posted image. Could that be what remains of the paint if your tank was painted? I wonder of early LOS Camaro tanks were painted.

  You are right, I went back out and dug out that Tank.  As you will see it has a bad dent in the Pass. front corner, I was trying to get out, with no luck.  I also found a small leak in the process.  So I am thinking of replacing that Tank, too bad!!!!
  It does have Black paint, just on the bottom, and it looks to have been "brushed" on.(and after the straps were in place)   I guess I had just considered it a "backyard" detail job.  Sorry!  I am attaching a pic.!

I have an original tank in my car and it is covered with a really thick coat of dealer installed undercoating. Its a Canadian car with the undercoating option on the options sheet. Should I remove the undercoating or keep it that way? I am not crazy about the look. It is just a 6 banger car. I would like to have a nice clean tank as the cars has just been painted. I have a new tank I can install, but is there any point keeping the original and does anyone care if this car retains its original tank. I was thinking of saving all of the orginal parts since this car is very original currently. Pretty well everthing for the most part is original except tires, paint, front windshield, some hoses and hose clamps etc.
